Best way to use Bistan in the Rancor Raid?

Problem with Bistan's TMR skill is that it isn't on his basic. You can't sustain a full TMR raid with just his one TMR skill. It has a 3 turn cooldown, which can be reduced easily by Frenzy, but Frenzy will still have 3 more turns to finish it's cooldown after you've used the TMR twice. You also need to keep in mind that in order for frenzy to trigger, the other characters need to use THEIR specials, not just a basic attack. Which makes it hard to repeat over and over with cooldowns. I honestly think Bistan isn't great for the rancor raid because of the niche that he fills. His base Potency is 35% which can be easily brought up by 30% (Mod sets) and another 24% (cross primary) which brings him up to 89% Potency. Add in some secondaries, you're over 90% and then you just need either 1 rebel ally or 1 debuffed enemy. That's all great and everything, but then you see that really theres a fairly long cooldown before you can repeat the whole cycle again. Having characters with basics that remove TM is far more efficient and repeatable. Plus in a team where Bistan is the only TMR, the 15% base chance of resisting will absolutely screw you over. Get resisted once and the whole thing goes to pieces. You need more than 1 TMR option, even with Potency as high as bistans.

Personally I think Bistan works better with a team fully of bounty hunters or empire in GW where its very likely that all of the enemies will be debuffed, giving him over 100% potency very easily. This allows you to mod him for speed and damage output, and then use his TMR skill to 1) take enemies with high damage back to 0% TM. or 2) use him for dealing damage (His special does a lot of damage) or 3) Adding DoTs for Zader to utilize.
