If you think I read 176 pages of QQing, you are wrong.

1) With Titans puddles.
It is fixed when he does it, so moving a BIT before he starts it, safes you (or the healer) some strain
You still just could level a Tank. Ex is harder than HM to tank, but way easier than DDing.

2) Knowing the fight near to perfection in meaning of when Titan does what helps a lot. I just kept mumbling his cycle and acted to that. Worked well.

3) Sometimes there lag spikes. Sometime so hard you cant even run out of the "red" zone during geo crush. Other times you have not a single lag issue, which is a bad sign for the following fight.

4) To me it seems like that with each new HM or EX instanced fight. You get placed on different servers. Thats the only reason that plasubly explains why I have in 5 fights 3 times near to 0 lag 1 time "normal lag" and 1 time such a bad lag that it is unplayable
