As it currently stands, Walk Off Hero is very difficult and frustrating for myself and many users. I think one of the main reasons why, other than the difficulty, is that it is mostly luck and/or a ton of gold spending (spent gold still isn’t a guarantee). There doesn’t seem to be any sort of skill involved and whether or not you get a hit hit is pretty much luck. Us players need something to aim/try for.
I think if you were to incorporate a target bash type element into WOH, it would add some skill to the event and make it less about luck. Each batter could get a random zone/target like target bash (extreme pull, power alley, up the middle) where if you where to hit the pitch into that zone, it would result in a guaranteed hit, or at the very least a GREATLY improved chance at getting a hit.
Also, off speed and breaking balls need to be more hit-able. Those pitches are pretty much guaranteed outs if that’s all that’s being thrown to you, with the extremely rare hit off a breaking ball.
