Heroes who can take advantage of the 1 sec cd aftershock will be strong. Mainly koshka, reza, maybe lance and ardan. Heroes with AS as their core items but cant take advantage of it will be weaker (rip alpha).
Base defences got increased, new defence items, overall wp and cp values decreased. Broken myth has more pierce, and pierce is more valuable now because theres more shield. That means more AS BM builds.
Spellfire has a lot more base damage now, so maybe its a good first item again for mages and non heavy cp users (aftershock builds) might pick up SF.
SC AS SF jungle lance. Im spamming him every game now to prepare for next update.
BP and DE are easier to stack up now, but have less wp/cp at max stacks. Maybe this will mean less hypercarry comps.
Stuns that were easily blockable (koshka, ozo) will be much more valuable now since reflex block has a 75 sec cooldown. Heroes who have a built in reflex block skill (gwen, malene) will be much more valuable.
TB gwen and midlane lyra will probably be strong, joule got a massive buff to her early game but she isnt so popular so maybe she will be a sleeper pick. Rip kruls damage reduction. Anka will still be meta in 3v3 lel.
