Let's make a check list of all of Maeve's abilities.
Cage - Disables movement completely. Basically immediate animation with barely a fraction of a second to react (unlike Bastardo's Leap). Basically renders any form of stealth or parry while inside 100% fruitless.
Cage Weakness - Nothing.
Siphon Life - Absolutely ridiculous range. Huge Damage. Health Restoration. Super Armor (ON A RANGED DPS).
Siphon Life Weakness - Stunning abilities only and nothing else. Melee attacks or combos do nothing, especially if the Maeve spams the jump button causing most of your attacks to miss (since she has super armor your combos are meaningless).
Vanish - Invisibility. Invincibility (lol so she gets both). Movement speed increase. Literally the perfect escape tool.
Vanish - Weakness. Can't attack. But who cares, that's not the point of it. It's an escape.
Toil and Trouble - Should basically be considered a one-shot to whoever it hits. Auto tracking and no range limitation. If it's canceled successfully she still gets to keep the ult she failed to use within the active animation. So just cast it again in a few seconds, since your opponent was skilled enough to stop you, you deserve to use your ult again.
Toil and Trouble Weakness - Line of Sight. That's it. Because disrupting the ult means nothing.
Passive - Full cooldown resets on a kill (Yup this is balanced because it's so hard to do on a class designed to kill things. Sarcasm by the way, it's absolutely broken). Has a mod dedicated to giving you 15% ult charge each time it procs. So every other character who kills get scrap (nothing) but Maeve can get 15% ult charge for her finishing blows while being designed to do exactly that?
I called it since the beginning that Maeve was broken, from the first day she was shown off on Stream. Almost all the devs playing saying ''Maeve is my favorite character''. Because of course a highly advanced super skill based character can easily be picked up by the average joe and give immediate value.
This is exactly why Maeve needs her ''advanced'' status removed, or get put in a position where her actions have consequences, period. It's almost baffling anyone even plays Gizmo (a ranged character that can actually be punished by melee combat, as she should be).
