yea that's pretty cool and kill cards like they have in both games are useful, it's just that I think it's sometimes too much to digest early on, specially during a gameI like this idea, but another cool thing in DotA is the way you can click on enemy champions (or friendly ones) and see their abilities just like you can see your own. Fair enough, it'll still take ages to learn how they all work, but that's something, especially in a game where you can't simply try out the champion you just lost against.
like I know what every champion in lol does, I'm not diamond or even a longtime moba player but I feel like I could grab dota and learn it if I spent enough time on it, it's just that these champion pools are such a huge barrier of entry that having a rough idea of what the dude that's in front of me does (what's his signature move? what's his role? what to look out for?) I think would be really helpful in a way reading his entire kit maybe wouldn't.
like, it's too much for me right now, new players are too noobish to really care about mana costs and cooldowns and crap. knowing that "BLITZ HOOK = BAD", which is kind of the advice a friend would give you seems to me like a lovely thing to have in the game if you're a total noob
