chromie literally has a longer cast range than the other heroes with whom you compare: how is that not directly an example of compensation?
By not needing to go in as close as other heroes, she can skirt the risk of getting interupted, pulled in, jumped on, and so on. Range of effect is part of a heroes power kit.
On the other bit, if you’re having waveclear issues – esp compared to raynor – on zul’jin, then I would think that a you issue: he even has two particular spec-paths for boosting his clear if so needed. However, given that zul’jin has quests for harassing heroes, having less a focus on clearing waves stresses a focus on hitting heroes instead.
Might wanna spell out the extent of the strengths you think you’re trying to compare to yourself before drawing incomplete conclusions that make it evident you’re leaving qualities out for the sake of short-thought topics.
