The seasons pass does not come with the mechromancer, you will have to buy that separately. Siren is fun to play as, I believe you can use all weapons so you don't have to worry about that and the phaselock skill is fun and very useful as support when playing co-op. If you tip Moxxi 15-20 grand then I think she will give you a corrosive smg, with 30-40 grand you will get a flame smg, both are good.
Yeah ive played some online with someone using her. yeah I will tip Moxxi more but I dont need any new corrosive weapons atm. I swear ive gotten corrosive smgs and assualt rifles and the cannot compare to the Corrosive Teapot Tiny Tina gives you. That weapon is my fav and best one. Plus I got a sticky longbow greanade does does corrosive and transfusion damage
Question about Slag. I got 2 awesome slag shotguns and a pistol. Do you have to use a different weapon when an enemy is slagged in order to do the more damage.
*if my friend didnt tell me I would have never knew but this weekened Gearbox is giving a bunch of codes for golden keys on Facebook and twitter. Just got 2 more keys just a sec ago before heading to work. Theres certain times though, so should check it out.
