I've done aby. Just not the void walker stuff. And I solo bastion. I do And when I did dominion or aby parties I actively played. And didn't go in till 80. I never leached and always left a party with a PL.
At first i didn't care till my skills suffered. I never got the hang of ninja because of PL. I tried to learn by reading, doing, training with my friends and simply couldn't keep up it up because of the stupid need of no risk easy mode. Same with healinbg. It took me time to get better at uaing what cure When.
Also you level itsn;t really importent it is are skill levels. Leeching makes you gimp and no gear can help ya. I rather get my skills in exp parties then rush to cap and then skill up. Skill up parties are so dull and mindless. Mindless playing bores me to tears. Your not real gamers/players if you do not actively play the game. So you have nothing praise worthly.
