This definitely isn’t a new issue, as another thread was found using a web search. But, it was flagged months ago and it still seems to be a problem.
Smite is quite difficult to use when fighting Lagon. For a smite-based character that’s pretty limiting. Trying to move the cursor to just the right spot in which to cast smite from wherever your character is standing makes it easier to wander into his attacks, as well.
Proposed solution: Give Lagon a much bigger hitbox and that would solve the problem. Since he’s supposed to be absolutely huge aiming probably shouldn’t be hard when fighting him anyways.
If that seems overly simple and too generous to players, for some reason, then just give him more hit points to help make up for him being easier to hit for smiters and perhaps some others.
I’m very much enjoying the game, overall, in spite of some hiccups along the way. Thank you for listening.
