Hi all, not going to make this a poll as I just want some feedback / thoughts on who would be the better option for my current roster and future progression. I'm sure everyone has their favorite overall, but personal bias aside, who would you R3 and why? Here's some background:
- Prestige doesn't matter for me - my ally is for fun only.
- Nebula is at sig 40 and Ultron is unduped
- I have synergies to consider with 6* R3 G2099 unduped, 6* R3 Warlock unduped, 6* R2 Hulkbuster unduped and 6* R1 Proxima unduped but I doubt I'd bring Proxima in most scenarios or bother to rank her unless she ends up making Nebula even crazier, which, with the faster ramp up now, probably won't be anytime soon.
- I think Ultron has an easy play style, that armor up buff is great and reliable heal
- Nebula was my first 6* and her shock damage is crazy good, but missing that armor up buff and there is still a lot of block holding to really maximize that damage.
- I'm not running suicides. Even though I have a team that supports them, I like throwing those specials. I literally put them on yesterday for 30 minutes and immediately took them off after remembering how gimped they make most of my other favorite champs to play.
Ultimately, it will come down to my own personal decision, but any blaring thoughts about what you would do and why?
