Yeah, I haven't played any other MoBa game buuuut I see that LoL is limited by it's simplicity in some regards. I mean, they have certain roles set up for years now but so lil division in stats and items that adding in new items or features can become broken on some champs that they were never meant to be used on.
I really wonder if, with how big these class changes are, they might make a new stat just for assassins when they roll out the assassin class rework. Seems like it would make balancing them and designing items just for them far more fluid because they would have to build something like "Dexterity/ Agility" or something to do their role well that would be useless on other champs unless they take some really off the wall not-so-useful build.
But I'm not a game designer so what would I know? LoL might be too old to do something like that at this point.
It depends. Adding more stats might be a good thing, but it will also increase the 'burden of knowledge' that League seemed against in the beginning(Being simpler than DotA 2 and how they pushed that back then, that it was easier to get into it). It seems to be going into something more complicated now though, what with the dragon changes, addition of Rift Herald, Elder Dragon, the new swathe of items being added over time.
Adding more stats will let them create characters that aren't tied to the current item sets-IE forcing Zed to build something like Agility/Dexterity, meaning getting items like Youmous or BC wouldn't be reliable as before, but they can also balance Assassins in a way that doesn't affect items used for ADCs, whilst item changes won't inadvertently be ridiculous on assassins when they're meant for ADCs.
Like, Suddenly Zed has to itemize with these Agility items that are tuned for Assassins like him. The downside is more things to balance, like mentioned Burden of Knowledge, and whether or not this type of change(Agility) would effect characters like Fizz, who isn't an AD assassin.
Then there's the lashback of 'you're changing muh champions' which I mean...people will complain about. It could work but again, burden of knowledge, as well as the amount of density they would be adding to it. The upsides are obviously, being able to balance assassins separate to tanks, mages, and ADCs because they have a different item set.
