FWIW; I'm having a lot of fun with stranger starkiller hatred maul in squad arena with maul at 5*. Unfortunately I see this team being better defensively in GAC which is a shame because it's a lot of fun... Won't be fun to go up against!
Not all Marquee characters that have been released are bangers (going all the way back many years) but I didn't mind the trickle feed honestly because it spaced things out well enough for F2P. Now I feel overwhelmed trying to figure out what new teams to build with the 6 remaining characters and not enough mods, relic material or ability materials, or any clue if these will be useful in future events to be able to make any kind of decisions on them.
I also want to highlight that CG is far from transparent about when we can farm the shards for these characters to get them to 7*, when the maul event will be back and what the requirements are..... Etc.
Overall I just think it's a bit overwhelming that we were dropped 7 characters all at once all going to different teams. However, that's possibly only unique to this era, and the next one being more focused on 2 specific teams will be better.
