How strong your guild has to be to beat HAAT?

It's not how much damage you do in normal anymore, that's not an accurate gauge at all. It's all about the team makeup of your guild. Here's a thread how my guild managed to do it, which we did soon after the normal raid nerf, which we finished in about 4 hours.

It's using the Super Team strategy, which is laid out in the thread and a link to the post so credit is given. We tried a couple times and failed, then I started taking inventory of what groups the guild had, like I laid out in the thread.

When we finally took it down, we barely had enough, and it was a real nail biter. Now we're finishing it without even really thinking about it.

I am in a play for fun guild and my guild can finish normal tank raid easily now.
I understand we are far from beating HAAT, but how can I tell if we can give it a try? For example, how well must u do in a normal raid before u try the heroic?
Thanks in advance and GLHF

I think your best way to find out where your guild is at is to give it a try. As a guild, we went from not being able to get past phase 2 to finding ways to limit damage so that everyone gets a chance to attack before we beat it in just 2 weeks. We used the same formula others have recommended.

Phase 1: attack with all of your Jedi based teams
Phase 2: attack with all of your clone/droid teams. (if you get stuck, use a few rebels teams one at a time to get through it.
Phase 3: Attack with all of your Empire, jawas, Chirpatine or Tie guy team, and taunters.
Phase 4: Attack with rebels and whatever is left.

Run a Heroic raid and see where you get stuck at. If it's 2, have all your players focus on droids or clones while working on their Empire teams secondary. If you get stuck on 3, then everyone focus on their Empire team.

You may also be able to call in some mercs to help you out the first time if you get stuck mid way through. That will also help you identify how much more damage you need to do and where. Failing sucks, but you really won't know how close you are until you try. The knowledge you gain is worth the coins you spend on it.
