I think it has all been said to death.... but wanted to register an opinion...
OML - the actual changes will impact players to varying degrees... some will be unaffected (no OML), some will be minorly inconvenienced (Strong 5* rosters or mostly 4* with under-levelled 5*) and others will have had their game utterly broken (Single high level 5* being OML, driving MMR and PVE scaling where he is now useless), and in case someone decided they were better off without, the refund is ridiculous...
OK, so I have not invested any ISO in mine, but at 5 covers (3 bonus covers after some heavy legendary opening) it has meant an opportunity cost (those covers could have been Thanos...)
I would get 1 token... so one random cover given that I have pricely 7 rostered 5* characters.... OML (5 covers), Black Bolt (6 covers), Thanos (7 covers), Black Panther (1 cover), Dr Strange (13 covers) Black Widow (13 covers) and Hawkeye (13 covers)... notice a trend... unsurprisingly my free token was not useful (random BSSM cover). So why would I sell the OML for 1 lousy cover that is almost certainly be unusable.
Carnage - What the hell....? what were they actually trying to achieve... they removed his one interesting power and replaced with the MPQ equivalent of a gentle slap with a wet flannel... whilst giving your opponent their own flannel to hit you back with... Seriously, no clue what they wanted to achieve. When 3* Storm does far far far more for just 4ap more with no downside you have a problem.
Elektra - OK, this change I like. some interesting tweaks that make her far more useful... at least 1 out of 3 is interesting, But she is still lower teir competitively. I just might use her more cos she has always been a favourite of mine.
I still have another week to decide on my OML. He is champed, but just at 450 exactly.I have seen how he is pretty easily handled now in PvP myself, but it is hard to pull the trigger on a handful of random, even with several of my 5*s sitting at 255 with 10-11 covers...
you need to pair oml with C&D. C&D ap generation is through the roof. you'll be firing OML yellow like Juggernault fires his green and red
