Hi Nic
At level 204, you're too low to be tanking endgame or near endgame instances, so in my opinion your best bet is to try to maximise your damage.
The obvious switch for me would be AI perks:
If you don't NEED 2 perks in AIT 2, then definitely put those in something combat related.
So for AI perks I'd do:
1 in mutate (for cause anger)
9 in CoLi
9 in CoNC
That's AI 19.
If you have more AI perks then you might want to think about how to boost DPS.
Wit (Atrox secondary 3) adds 60 dmg for 30 seconds which is valuable
if you have 5 more free, stick em in to mutate.
The 6th perk in mutate isn't great since it checks MC vs NR, but with reasonable AAO it can land in PVM fairly reliably. It doesn't do a lot of damage and it's on a long recharge, but its ok.
Alternately you could sink all your free perks into atrox primary - body slam isn't THAT bad - it will do 2500 dmg with 10 perks in the line which is respectable, albeit a slow perk :/
Enforcers don't get a lot of damage perks unless you go 1HB/1HE - but you can get nearly the same number of damage perks by branching out a bit:
brawler, for example adds dmg and gives two damage perks with a 4 perk investment.
imo for SL perks you could do:
10 blunt mastery
10 coon
4 brawler
At 204 bioshield line is obviously nice for soloing and a bit of team support (I spam bio rejuv on CD), and if you're smart you can use it to your advantage to boost your DPS as well: perking all the way gives 3% reflect and 80 damage shield, popping bio shield will boost your damage shield by 120, add rage for another 95 dmg to 295, add ice burn for 70 more, and use
Violation buffer to boost your damage shield by 60 more.
Now you got:
Say, 25 shield in symbs,
80 in coon
120 on bio shield
95 in rage
70 in ice burn
60 in procs
= 450
And if we had a 300 tower site you can plant a cold laser tower for another 50 for a nice round 500 damage shield.
Now the trick to damage shields is you need to get aggro to use them, so, now taunts start to matter.
If you're fast with nano absorbs, got decent AC's and got all your standard items up (i.e. 13% reflect graft), you can mitigate damage down to a level that is exceeded by your damage shield - that's what you want. So, if you can get your damage shield up really high, it means you can start padding the fuck out of your damage. Weaps? sure, but imagine that each hit your weaps did was affected by 500 add dmg - that's no small amount, so get your procs, buff up and tell the mobs to come at me bro!
So, now, even if your weaps are sluggish, and you got only moderate add dmg/crit, the best thing to do is boost your taunt: scorpio's aim of anger is ideal, and mutate 1 (cause anger) paired with max psychology are the best tools at your disposal. if you don't have scorpio aim of anger, you should use the scheol quest taunter which does I think about 3600 taunt every 10 seconds
Ephemeral Annoyance 3600/10s
Jealousy augmented aggression enhancer 1800/6s
Scorpio's aim of anger 2000/6s
All good items for agg generation.
