I have 2 BH's at 50, one is a PT pyro and the other is a Merc Arsenal. I started with the Merc because I wanted to PvE most of the time and thought a ranged AC would be 'easier' in some regards. However, I really got into PvP and following a nerf to the AC (which wasn't needed) I started the whole game again as a Powertech. I abandoned a War Hero to do this so it wasn't an easy decision, but frankly the PT Pyro was worth it. With 1.4 on the way the PT Pyro will now be nerfed, but so will the Merc. I'm not really sure what to do. I want to play BH but Bioware are messing with things everytime they release new content. Arguably I should be choosing an AC for more important reasons, like the playstyle or the feel of it... I've played MMO's for a long time and I am well aware that this 'feeling' doesn't matter much when your beloved Merc is repeatedly beaten by opponents who have the odds stacked in their favour. I will probably stick with PT Pyro and un-sub if the changes are really as badly planned as I, and most of the community, expect them to be. So, my advice is: toss a coin.
