Oh woah, yeah, that sounds rough... I can't talk, I haven't personally seen it chained that often since 0.3.0 came out - with the improvements to DI and the additional knockback from repeating the same move multiple time, I was seeing/getting 2-3 consecutive hits of it at the absolute most, before people just slide out sideways at immense speed.
Before this update lightning strike would be reppable about 8-10~ times before needing to reposition. And it's incredibly resistant to DI for some reason.
This update made it so it'd be about 3-4~ before the cowboy needs to teleport or whatever which makes it much less painful. By all means the problem still remains. The move is functioning in a particularly goofy and antithetical manner. But I'll take the dub regardless.
