This is a long post; asking for long replies, so skip it if that's not your thing! Name-checking a few folk who tend to give solid advice, with thanks @DNA3000 @will-o-wisp @MegaSkater67 @DrZola @Lvernon15 I'm a fairly slow FTP solo player; gaining a few extra awards from running a one-Man Alliance. My big blocks are my slow acquisition of T2A and T5B, so getting champs to R4/R5 is very slow. On the plus side, I don't really need defenders; and Prestige simply isn't a thing for me at all. I don't run suicide masteries.
I completed Act 5 a while back; and have been kind of put off from attempting Act 6 due to the 5* Gating, and the obvious general discontent on the forums about various aspects of it. So I've been exploring Act 5 and dipping into the Variants.
However, I've started to build up a bigger 5* roster, including some counters for the big Act 6 bosses I've been reading about (notably a 4/55 Warlock just one T5B away from maxing out) and I'm not far off exploring Act 5 as Elders Bane; so it seems to me that Act 6 beckons.
My current top tier looks like this:


Clearly I've got a few heavy hitters, and some solid Power Control/Immunity options, although my best immune champs are robots, which can be disadvantaged with certain nodes. My DoT champs are a bit more limited (mainly a 4/55 X-23, and 6* 1/25 Carnage), and I don't have much buff control. Some utility provided by GR, Warlock, Stealthy and She-Hulk.
I've pulled several decent champion options in the last few months, but can't rank them all up; and the question is: how would you recommend developing my team further for Act 6 and Variant content, given fairly limited rank-up resources?
Importantly, I do have 5*Awakening Gems for Mutant, Tech and Mystic available; plus I can probably get another from rifts. I don't plan to turn on suicides, and lack important synergy options like Nick Fury, The Champion and Heimdall above 4*.
Looking at the champs I haven't built up yet, the most obvious options to build up and/or Awaken (as well as the obvious CMM and Warlock) are:
Team build - option #1 (Literally both pulled last week):6* Rulk and 5* Domino
Team build - option #2:Some or all of - 5* Sabretooth, 5* Omega Red, 5* Void, 5* Killmonger
Strong stand-alone options:
- 5* Colossus
- 5* Iceman
- 5* Thing
- 5* Dr Doom
- 5* Dr Voodoo
- 5* Venom the Duck
- 5* Rogue (I love her, but pretty clearly, she's the weakest of these options)
If people can offer explanations that'd be great. I've been around long enough to know that Domino is a great champ (as are most of those I've mentioned); but given that I've already got a 5/65 Havok and a 4/55 X-23, is she really my best bet? In Act 6 and Variant content, might Colossus, Omega or Sabretooth bring more to the team?
Likewise, with a 5/65 Ghost Rider, 4/55 Vision and 4/55 Magik (who has a really solid synergy with Warlock) available and ranked up already, is Dr Doom (Awakened or otherwise) really going to be a transformative champion? Or is he genuinely so good that I'm crazy to even consider Awakening Dr Voodoo instead?
If you were me, which 2-3 champions would you be taking to R4/R5, to get to grips with Endgame content?
Thanks for reading (those of you that stuck with it this far! 😉) and for any advice you feel like giving.
