Some wesker tips
These are more or less just tricks I picked up while playing and noticing how wesker really works.
The throw: This is,imo,better than his choke slam into a wall. The reasoning is simple,he flings you FAR and if you hit a wall then you're gonna get instadowned because he recovers fast enough to Go for a lunge right after. Even if you don't get damaged,you're still infected which is actually a huge concern with wesker because that means you're gonna eventually be 1 shot and slower until you heal.
The slam: This is the more common use of the power,A neat way to use it is when you see a survivor trying to make a break for a pallet,know your timing and spacing and you'll always catch them before they can drop the pallet. Also I recommend that you mainly use the dash in general when your target is in a narrow path,weskers hit box will make it incredibly hard to escape him in that situation.
The smack: So in case you didn't know,wesker can whack you if you're in an animation where he can't snag you (Vaults and Hopping lockers) so in this situation,the ability works as normal except instead of grabbing,you hit them. This damages and infects as well (will 1 shot if the survivor is fully infected btw) so don't be afraid to let it rip if you see them going for a pallet vault or window vault.
Above all? Keep everyone infected,the penalties are huge and they'll be forced to use up first aid sprays (which there's only 12,after that it's gone for good) and this also works to slow the game down as well.
