Turn meter question

1) I seriously doubt that Wat took turns for 90 straight seconds. That said, he assists any time an ally with tech uses a special (and removes 15% TM). Nute and Asajj both have multiple specials. One of his techs grants TM to whoever he gives it to. The whole team will gain 15% speed for each enemy with extortion. Asajj will probably stun some people, causing them to miss turns. Asajj also can remove TM from you with one of her specials. I suspect you just got TM-trained, and Wat would have been assisting the whole time.

2) A genius in your guild TM-loaded the team. Now you know why your guild leader has probably been yelling at people not to TM-load teams.
