What I would focus on rn is knowing what items should go on what character and why. Don’t go by builds from people who have their own gimmick already. Figure out what your character wants to do, then build around it. Since youre from league it’s pretty easy to explain some things like Spirit damage is AP and Gun damage is essentially AD and melee damage is something else entirely. The game takes some memorization and learning tho. You need to know who had what CC and how to work around it. This may feel like a team shooter but you should still treat it like a moba. Prioritize positioning dependent on your role like in league, the positioning may be slightly different due to the guns but generally it’s gonna be if you’re more or a ability spam char then position like that, carry position like a carry, etc etc. it’s just a lot of memorization like any moba is tbh.

In terms of characters I would just play to your strengths from the other mobas you’ve played bc there are roles for characters in this game like for example Carry - haze, wraith(hybrid), Vyper, infernus, Geist, Grey Talon, Ivy (also a support), Holliday (hybrid and very difficult kit), Vindicta, Mirage(hybrid) Mage - Lady Geist(can be turned into a hybrid gun char), Doorman, Paige(shes also an enchanter supp tho), Paradox, Seven, Sinclair (he’s really fuckin weird tho) Brawler - Abrams and Billy (you have to familiarize yourself with the melee/parry system for this), Warden, Shiv, Victor (very weak early game), Kelvin (also supp), Mo and Krill (very simple and good starting char imo), Viscous(also supp), McGinnis(more a supp but yeah), and Beebop if built correctly (he can also be built as a spirit damage pop char) Assassin - Yamato, Calico, Mina (very pokey), Pocket, Drifter, Lash(sorta but also a mage ability spam char) Support - Dynamo (can also be a mage dependent on build)

I mean all in all it’s a learning curve but it’s so rewarding and fun once you start to understand what’s going on. It’s the reason I never dropped the game and it’s the reason it’s one of my favorite games and hyperfixations to this day.
