As a SWTOR Player, no it will not. My Guild is sorely disappointed by SWTOR as of late, Makeb promised way too much and is not going to deliver nearly half of the promises.
SWTOR Is gonna flop again, hard. They promised same gender romances, (take note, plural) we're getting one each per faction. We were promised a 'unique' experience for classes, because they are not continuing individual class stories anymore (which is a HUGE disappointment, they were amazing and I loved them, this put me off SWTOR big-time), there will only be one voiced storyline for Makeb and there is nothing making it 'unique' to our characters, aside from how they address us in the beginning.
However, I personally prefer SWTOR's PvP. I can't really explain it too well, but I find it a little ridiculous in WoW how I can go solo like 4 players and come out on top. On SWTOR I can't really do that, and as a PvP Healer in SWTOR, one heal will not heal someone up to max. I find PvP healing in WoW a little ludicrous... I can keep myself and others up just by spamming one heal at low level, eesh. (I just came back to WoW last week pretty much, I haven't hit 90 yet so this is from a lowbie perspective, last I played was Dragon Soul patch.)
I love SWTOR but no continuation of class stories ticked me off big time. I played SWTOR for the unique stories and for the wonderful people I met on there, we're all Star Wars nerds there and I found a really, really amazing Guild that slowly died out because of drama. The remaining friends I have on there are gonna be quitting as well due to no continuation of class stories, we weren't much of raiders, so yeah. Don't get me wrong, Makeb is new content, new raids coming... but... Meh. It's not... amazing. It's... underwhelming. I will not be buying it and am now playing WoW again (not too much to my enjoyment, I'm just going along doing my own thing with my Bf, who I met on SWTOR, we're both disappointed about it right now. We loved raiding and PvPing together but our Guild died and honestly, since F2P hit, the community became pretty rotten. It's like WoW's now, tbh. Rarely do I meet good people anymore.)
Sorry for the long wall of text but this is my experiences. I would suggest playing SWTOR for the amazing stories, though. I've fully completed all the Empire ones and I truly loved them, I dabbled a bit in the Republic ones but it feels weird playing Republic, heh. The leveling experience in SWTOR was really fun, I loved it the whole way. :)
