Well, I can't really help you with the uber high-end build as I usually use cheap builds, but I can tell you now that you're likely going to want a different primary if you want to solo AVs. Plant/psi would be an AoE monster in regular play, but plant/ is not very suited to fight AVs.
Soloing AVs on a dom is very difficult - basically because they're nearly immune to mez, and doms don't get the passive mitigation necessary to survive against an unmezzed AV. The only way I've ever heard of doms soloing AVs is to get a mega global recharge build and getting the cycle time on their ST hold down low enough to overpower the purple triangles. However, in that case, the cast time on the hold becomes very important - a difference of a second in cast time could make the build twice as expensive (if it is possible at all). Plant's hold has a 2.07s cast time - it's going to make this much harder. Generally the thought is to use mind/ or fire/ primary, as those two have much faster casting holds (1.1 and 1.07 seconds, respectively).
As for the secondary, /psi doesn't have the best single target damage, but it does have drain psyche to slow the AV's regeneration (it shouldn't floor a level 50 AV, but it'll chop it down to perhaps a quarter of its normal value). With a mega recharge build it should be perma, so I think /psi should be able to do it - but you'd probably want to ask those who have done it.
So, long story short, plan on getting hasten and as much global recharge as you can possibly manage, and consider using fire/ or mind/ prrimary instead of plant/.

Ah, in that case AOE must be more of what I want, I really want to be able to kill lots of things with no problem
If you're mostly looking for AoE carnage, any combination of fire/, plant/, /fire, /psi, and maybe /thorny shoud be pretty decent. I'm not familiar exactly how their relative power levels break down at the highest levels of investment, but they are all sets which are strong at AoE.
Plant has probably the single best AoE control in the game in seeds of confusion - and that one also clumps up foes and gets them to weaken each other. It also has carrion creepers to dish out some extra AoE damage (which will be perma on a high recharge build) and the AoE immob for plant does twice the usual damage (making it a useful AoE attack).
Fire has hot feet for good passive AoE damage, and high damage pets. Bonfire can also be used for its DoT (about 60% that of hot feet) if you are willing to keep spamming fire cages for the -KB (which also will add a bit of damage, especially proc'd). Less control than plant/, but with permadom flashfire should last long enough. The purple build up proc in fire imps would also be quite good, if the devs fixed the bug that kept it from working (has that been fixed? don't remember).
/Fire has two pretty good AoEs, and fiery embrace is a strong damage boost (especially on a high recharge build, and when combined with fire/ and hot feet). Fire also has strong single target damage.
/Psi has quite good AoE damage - while psi shockwave still comes late and isn't as good as it used to be, psi scream is now worth using and the rest of the set isn't too shabby. Not as good of single target damage as fire, but much better than it used to be. The set also has drain psyche for some interesting health and endurance related trickery. No damage boosting powers, though.
/Thorny is a bit of an odd duck. It has a good PBAoE and two cones (one melee, one ranged), and thorntrops can also be used as an AoE DoT if you have something to keep the foes in place. It also has aim for an occasional damage boost. The set is hampered by some long animations, though, and has only average single target damage. You also have to deal with redraw. This isn't really a popular set, and I don't know how well it stacks up at high recharge levels.
Of these combinations, fire/fire and fire/psi might also be able to do AVs at high enough levels of investment. You'll have to talk to someone more familiar with high end dominator IO builds for the fine distinctions of which of these is most powerful, however. I would still imagine that any of them ought to work though.

Awesome, I'll start looking into plant/psi or plant/fire then, and begn experimenting with builds for the 2
So since people in here are likely to be dom experts, and I have yet to make a dom, I'm hoping I can get some build help in mids.
Now what I'm hoping to make is something that can solo really well (not like i'd know if they can solo well anyways) and preferably something that can take down AVs alone.
In short i'm looking to create a killing machine because what I favour in characters is pure fighting ability. Now I don't know what sets would accomplish this best but I heard from a dom friend that plant/psy is good for this.
So if anyone can put together an amazing plant/psy build i would be really grateful, or if you think that something better fits the bill of uber inffamy-making machine, that'd do nicely.
And also, don't worry about keeping the cost of the build down, I'm just looking for the greatest possible build.
Well thanks for any help in advance people
