I have tried to like Beam Rifle, tried different ATs, different builds and I just can't do it. It's so weirdly slow. Has odd delays in firing and animation.
Did a Dilemma Diabolique Trial yesterday with my beam blaster. Was only blaster on league, asked to deal with the Lifegiving Essence. But it was so slow shooting them I could get them all in time. Thank goodness there was other ranged toons on the league.
Yeah it hits hard and is great on AVs and pylons, just don't do anything else I guess.
Of course I'm a just bitter old man that spent to much time and inf into these damn beams
