This wipe is going to last five months roughly as of a few days ago. The skill XP changes have essentially made those who cheesed their skills have a major advantage over the rest of us who won't ever be even relatively close to those that did because they cheesed them before it was patched out. I was fine with the change when it was initially added as I figured a wipe would happen with two months. Now though since we know of how long it will be, I find it highly unfair to keep the skill XP changes as they are.
Players who have cheesed their skills can gap close much better than those of us who haven't. This is even more so noticeable in labs for example when people bhop down a hall after tossing a nade to give them the few seconds they need to move.
I personally haven't ever been hurt by this, but a friend of mine I play with did cheese his skills and it's insane how much of an advantage it gives him over people we fight. He plays very aggressively and especially with the influx of new players, he literally just runs people over as they can't out run him, and they don't expect him to be able to get to certain spots/angles as quick as he does.
tl;dr – Revert the skill XP changes until the next wipe so everyone is playing on, or can realistically be on an even playing field.
