Yesterday was far too busy a day (12th wedding Anniversary & trip to the VA Renn Faire with the kids) to post anything, but the day before Aggro got some playtime.
Fun.
Got him suited up with a full set of DO's (thanks to his "big sister" Viri), and started working through radio missions in Steel. Had a total blast soloing hellion and skull missions at 8X/+1. I had so much fun doing a "bank robbery" (not the safeguard mission, just a radio mish in a bank) with the skulls that I ran it several times. I happened to be in the lobby area when the two ambush spawns appeared... MAN it was a good thing I had a full kit of insps on hand! with 3 luck running I was able to corner pull the entire massive pile of them, lock then in place with Roots jump out and Confuse most of 'em and then pop Hasten, AM and 3 reds and start spamming roots on the lot. Repeat SOC as it was up etc...
VERY close, but I was still standing at the end. :-)
Anyway, Aggroactive is now up to 15.something with a build looking something like:
Strangler (1 acc)
Radiant Aura (1 heal)
Roots 6 slotted (3 acc/3 dmg)
Swift
Hurdle
Health
Stamina (3 endmod)
Rad Infection (1 -def)
Super Speed (1 endred)
Seeds of Confusion (2 acc/2 conf)
Accelerate Metabolism (3 rech)
Enervating Field (1 -end)
Hasten (3 rech)
I'd put it up in mids, but that would mean bringing up parallels, and I'm doing too many other things atm. 
Anyway, Plant/Rad is a major success so far. Easiest character I've leveled up mostly solo in quite a while.
I love plant. I have a lv 50 plant/storm/earth, Goddess of Nature on Liberty. I think of all the controller primaries, I enjoy plant the most. My illusion/rad feels more epic and powerful (plus the build was WAY more expensive), but I love Goddess more just for pure playing fun. I've tried Earth, Ice, Fire, and plant comes out as my favorite. Keep posting!
Update: Tsoo STILL suck! 
Aggro has been working through Kong Bao's missions trying to get the spelunker/fortune teller mission. So I hade the wonderful experience of hitting a mission with two spawns (one Trolls the other Tsoo) that were essentially intertwined. On 8X/+1 that was a total beast. I think I died more on that mission than I have in all missions so far put together! It was fun though...
Aggro's up to about 17.5ish, picked up Spirit Tree at 16th. I have to say I LOVE the tree on my Plant/Storm as it's the only self heal I get outside of the medicine pool, and slotted with a 5 pack of Dr. Wounds, it makes quite a bit of difference when I drop it at my intended kill-box before I start.
On a Plant/Rad I was expecting that it wouldn't matter nearly as much (given /Rad's self heal ), but I'm finding it still quite useful. I really think the 'Tree gets a bad rap. It's not suitable for use on a fast moving steamroller team, but it's DANG useful when soloing really large spawns at the limit of what you can handle. 
So... Round three of my Plant/ controller journals. Aggroactive goes, well... Active!
So last night I started playing my third Plant/ controller build, Plant/Rad.
VERY fast starting build. At level 5 I headed to Perez and started using the "medic" there to power up for a street sweeping blitzkrieg to 9th! Amazing what a level 5 Plant/Rad can do when he pops 1 Acc, 3 Def and 3 Dmg insps then lays into a spawn.
Anyway, the combo of RI, Roots and Seeds of Confusion is just sick. KNowing both sids of this build pretty well, I can project about what it's going to be like playing it in a few levels and it's going to be a BLAST. I'm already doing X6/+0 w/o boss missions (though I do die when things go pear shaped, that just makes it more fun) at lvl 10... Adding actual enhancements and a couple other key powers is just going to make it extra cripy tasty goodness.
About lvl 11 now, and loving the combo... Hate Lost and thier PITA sleep, but who doesn't?
