ppl are unwilling to dodge her shit after a ding and her shit is heavily dodgable if you arent getting cced
I agree with you, in ideal circumstances (ie: the lane, when she's visible, etc) the orb and missiles are relatively dodgeable. My question is when are you in a team fight that you aren't cc'd, though? Nearly every hero has a slow, bare minimum. The slow is all it takes to put a hero without a Barrel Roll/Vault/Blink from being a possibly hit target to an easy target. If you're the tank, melee, or a shorter range hero you can forget about it when it comes to dealing damage against her. She either has to be distracted and aiming in another direction, or you pretty much have to eat it as you chase her never-ending blinks or whoever else on her team you're after.
It's not really as simple as you make it out to be, which is why she is banned in every HL game nearly without exception.
Another thing is that ppl arent reluctant enough to provide her oppurtunities to be effective, sticking around her while half-health, etc.
Most heroes go to half health or thereabouts (or less) in one combo from her, nevermind the other 4 heroes trying to do damage in a team fight. So if you're engaged 5v5, you eat an orb, you just peace with half health? That's a good way to get flamed for abandoning your team, and completely opposite of how you play versus pretty much anyone else sans Greymane or old Chain Bomb KT.
The range on her stuff is ridiculous with her mobility. The ease with which she can talent into teleport and escape/sustain is pretty insane. She should never have the damage she does with the teleport to begin with. It should be less teleports = more damage or current teleports = less damage. Then, after you get all that out of the way, the resets are what really make it crazy. All it takes is one of your teammates getting caught and combo'd and she can just clean up your entire team with a reset, or get you all so low/push you back so far that it's a virtual wipe and free map control for her team until everyone hits the base.
I honestly don't think the complaints on Li-Ming are overblown at all. I can't even imagine what a fucking shitshow it is playing with her in lower MMR tiers where you know no one is dodging anything and it's feed city due to how much everyone likes to fight over every objective.
I really think you should hop into HL finally. You said you were never interested cause of lack of bans IIRC, well they are here. Hop in there and get some non-QM non-ARAM perspective. The game is much more enjoyable without her in it throwing bombs every few seconds.
