Champion Buffs, as opposed to full reworks.
I think Kabam can do some slight buffs to improve some champions, as opposed to full reworks like the recent She-Hulk and Spider Gwen. The reworks should keep coming for trash tier champs. But I think Kabam should do some more simple buffs to improve lower-mid level champs.
My suggestions:
Magneto - put possible 2nd bleed back on his SP1, make bleed on SP2 100%, lower attack rating by 50% when Magnatize is active. Also, scale up his sig to get down to 5% at full sig.
Ant Man - put Fatige back on all basic attacks. Make Poison do double the current damage. Also, all Fatige should have a 2nd effect of 5% chance to make Evade fail. (This would help OG Cap as well, but his % should be more like 50%)
Iron Fist - give Armor Shatter when 6 Armor Breaks are stacked. When opponent is Armor shattered have Weakness proc when he would cause an Armor Break.
Electra - cause Armor Break even if another ability or node (not just Native) caused bleed immunity.
Loki - just a simple attack increase, maybe by 10%
X23 - remove the 5 bleed cap (plenty of champs now have insane Bleed). Gain cruelty even if another ability or node (not just Native) caused bleed immunity.
Civil Warrior - raise his Block Proficincy and Perfect Block up to the same level as other Caps.
Karnak - increase SP1 damage by 300% to bring it in line with regular SP1s and double the True Strike time.
Psylocke - EITHER give her regular power gain (not -25%) OR take away giving the opponent 5% power when a charge is lost. Not both.
Thor Rags - give opponent minus 5% power gain for each Shock debuff.
This is a quick list I came up with while thinking about it for a few weeks. Any suggestions you want to add, please post. Hopefully Kabam will notice.
