First Time Tanker!

Lots of great help again, I am currently sitting at lvl 10 trying to figure out how to build and slot. I have read over so many fire builds and wall of fire page. So far this toon is really fun to play and soft for now. I have noticed that acc & end seem to be major factors more than my health for now. I am running as much as i can through mids hero designer to try and see what is best and affordable. I have taken combustion is that a power i should drop?
Thanks abnormal_joe for the guides have read through them many times to try and get a better handle on what my role will be with this build.

If you're planning to solo, my advice is to concentrate on attacks. You want defenses, of course, but given as you don't get attacks as fast as an AT that gets them in the Primary, you can't really go wrong by picking them up as fast as you can. Get yourself into the 20s, and then you can start thinking about buffing up defenses. You'll need the damage to get to those 20s in the first place.

On a team, though, you'll want to make sure you're tough enough to take on what's coming. If you think you can rely on buffs, you can go ahead and stick with an offensively oriented build, but there's also dual builds to consider. You can make one build offense and the other defense. It costs a bit more to outfit both with Enhancements, but that can still be cheaper than going with expensive all-IO builds.

I would recommend Invulnerability, Shield, Willpower or Fire. Those are all good strong offensive sets that do well solo. Fire is so offensive you may not even have to lean that way. Invulnerability doesn't seem so offense oriented, but in fact with the +tohit from Invincibility and the End boost in Unstoppable it really is.

The other bonus to Invulnerability is that it will hold aggro much better than Willpower. Personally, I think SS is a good combo with it, it's an obvious match, and with Rage's +tohit stacked with Invulnerability you almost don't need to slot for Accuracy.

Fire/Fire or Fire/SS is also a good combo though. I've also become very fond of Dark, both Primary and Secondary. That's more about control than damage, though.

I have also found Fire/Electric is not bad at all the knockdown/up of Electric is very helpful in helping mitigate damage.

I have a Fire/Ice but I know half of the time the only reason why he survives is due to Healing Flames and Ice Patch.

Fire Armor may not be the sturdiest of tanker primaries but it is solid enough for most applications, and a far better soloist than most.
The changes to FE mean that you can really pump up that burst damage to deal with a particularly pesky foe.
I've leveled this particular set to 50 three times now.
The fire/ice tank did indeed rely heavily on Ice Patch for mitigation. Once I had him softcapped to melee I found the power redundant and ended up dropping it.
The only real threat now is a serious -recharge debuff. Since I retained a fully slotted rez/nuke I tend to use it to shed the debuff and slaughter the foe who had the temerity to challenge me.
The fire/ss tank went through quite a few different builds: +hp/regen, max dmg, and finally softcapped typed defense. The final build really shines, particularly once the end usage was balanced out.
The third alt was a dm/fa scrapper that went damage all the way. Its a race to see who drops first me or my enemies, but I have a ferrari to their pinto, and I can always rez they cannot.

In all three cases a surprisingly large amount of the damage mitigation is the ability to wade in pop two or three aoes then my heal, and have only one or two foes still standing.
A fire/fire has even more of that damage potential if less active mitigation.
A team makes things easier for me by contributing buffs and their damage, but I manage just fine on my own.
