Considering this dueling tournament:
I'd hardly say ops are still #1 (all things being equal), imo it's engineering sniper right now. Ops were so much better in 4.x, but now since 5.x they have basically stayed the same while other classes got really good buffs, just look at mercs for example. Imo, 5.x was an operative nerf in that they basically got nothing at all of any *real* consequence, while other classes got buffed - leaving ops behind somewhat.
With that complete heal bug in the utility tree, it was somewhat doable. But now, there really isn't anything making ops better than they were in 4.0. Such is life playing games, tho - it always seems like game companies make bad balance decisions. It has held true in every single game I have played since 2000. The only thing to do is try adapt (and deal with the ********) or play something else.
