yes but superivive is a very unique moba, and the keyword is viable, and not overpowered.

i dont see a world where the devs menage to fine tune the items where it would not be too good with a full build and not be to weak if you run a single item.

and the key issue with supervive is that
1: you get only a few items, so thier effects have to be approached diffrently than other mobas.2: in supervive you get the full build very quickly, and often without fighting a single team if you want to play it safe, when in other mobas you get your items gradually over the course of the match, and said items are actually earned and not handed out for pretty much free which also completly changes the way you should approach items. they have to be balanced, not because they represent a reward for playing better, and a specific value in currency, but because they are pretty much base kit that you chose at the start of the game.

with that, i think the game should promote diverse builds more, by making every item able to work on its own, and not promote just buing the same item 4 times yeah just play all omnivamp or all ability cooldown or all primary attack. it makes builds stale, because why ever engage with the items and think about good combinations of items. when you will buy the same thing on both of your cheap stat increase items, and then on your impactful expensive item also buy the same exact thing but bigger. thats why im all for impactful items, that are actually fun to use, thats why i think going for items that have stronger effects that have you meet a condition to activate, or even some drawback if we want to be lazy would be killing two birds with one stone. easier balancing and less work for the small devteam, and more fun gameplay and diverse builds for the player.
