Hey guys, just had a question regarding hero skills.
Heroes get access to all your unlocked account skills, as soon the hero is unlocked on a character, right?. That made me think, what exactly is the point of [Hero Skill Trainer]s? Wouldn't it just be easier to buy the skill on one of your characters if you want your heroes to access it? It also seems these hero skill trainers offer (and accept payment for) unlocking skills you've already obtained on your account anyway.
The wiki page on hero skill trainers doesn't really cover the above, and I'd be keen to know if there are simple things I'm missing somewhere regarding skills and heroes!
