I've been debating whether I want to switch out Solomon Grundy for Batman in my red son team. Batman has better stats, but I think Solomon Grundy has a slightly better passive.
However, switching in batman would make a very powerful offensive team, and I wouldn't consider taking any other character out of my red son team because it doesn't make sense. Take out superman, and they just have average damage, take out WW, and I can't put out specials as quickly, which is the key to Batmans advantage. I'd like to know what you guys think, as many of you are a lot more knowledgable than I am at this game.
personally, I like RSSG with RSSM and RSWW. I think RS bats works nicely w/ RSDS.... mainly b/c RSDS's level one hits 3 times and you'll get unblockable each time w/ it. plus, it makes RS bats very fast. RS bats is, unfortunately, maybe the worst RS character, but it's still cool to have multiple RS teams now.
but if you don't have RSDS, I still think RSSG is better w/ the original RS team.
