Not in every case. You can have somthing on farm. But if you come into a grp that do a tactic you do not know and never have done before, you get in struggle.

For me, in T6 I only know how to handle LoS and Superslug. Don't have any experience in handling the other tactics. I'm shure I will not get it in first try, if some party begins with another way.

In T7 I did learn some different tank spots and ways for Renaud handling.

T8 is really interesting. I did practise it for many hours last weeks. From my experience, replacing only one ppl will lead to a fallback of 20-50% at beginning. Even if that ppl have kill exp.

T2. I was never in a group that did not the enrage method.
