>>48403033Confirmed for never having played battle tower. Even in gen 2 there's a strong enough distinction between PvP (including tower) and PvE Pokemon and movesets, and you're going to suck hard cocks unless you use smogon OU tier sets and strategies.
For people who love gen 2 battle tower I recommend playing Crystal hack called God of Arena that focuses solely on battle tower-like facility, it has some nice features that make it less annoying to build teams and player is required to win virtually hundreds of battles before you beating the facility completely.
