I play a bots/traps. I've done four Apexes and three Tin Mages thus far. For most of the content of either, I've felt that I was pulling my weight. I focused on control and debuffing, and used my henchies as disposable canon fodder. They still chewed through most of the enemies relatively easily, and I rarely had to resummon my protectors or assault bots outsde of fighting pylons or AVs.
The battle maiden fight causes me to have to resummon constantly, and my bots really don't do that much to her. However, they allow me to get in close to her in bodyguard and drop poison traps on her feet. With a little luck and persistance, I've been able to keep BM in the poison cloud nearly constantly. On one of the teams, we had no other -regen debuff, and weren't able to nick her without the poison trap.
On the whole, my bots/traps seemed to have less trouble with the Apex TF than the average scrapper.
For my only apex attempt we had 3 scrappers, 3 tankers, 1 blaster, and me a bot/traps.
oh and my pets died. horrible horrible deaths. Even with my high recharge i just couldnt keep them up often enough to do anything.
After spending about an hour bashing our heads in trying to do a 'move around' tactic, i decided it would just be best to play rotate the blue fields of death. What i did was immobilize BM, and we rotated the fields, when they were on her, we swapped to range attacks, when they werent i toe bombed poison trap, and acid mortar, and did we got her down pretty quickly.
It just took FOREVER to figure that out
