Idk if it's still the case but it was so cool when people would look forward to certain TT/GHB units releasing and actually being useful for your team, grail projects were my favorite thing during that time. Makes it especially baffling when they release modern ones that don't even have prf weapons

Year 2-4 character/team building was just insanely fun to me, aside from arena scoring it felt really satisfying to do all the content/get high rankings with just units you liked
