Just came across this thread recently and I've thought a bit before I answered.
I don't think we DESERVE a more punchy laze-target. Would it increase our overall dummy parse DPS? No. But it WOULD give us yet another advantage over less well-endowed classes on particular fights, meaning more reason to take a sniper (or a second sniper) over, say, a sorc or an assassin, classes we already have beat in most regards.
For example:
Kephess the Undying - Increased burst during downed phases, more total DPS, less difficulty pushing to 10% before the last pillar comes down (though admittedly not a hard fight to manage that in the first place).
The TFB - Super fast Larvas go down a lot faster 2/3 times with this change, assuring an ambush crit once very 2-3 minutes.
Thrasher - Already a backup for the melee DPS not being able to get to the demolitionist because of MM's Diversion, we could theoretically hold Laze Target and bring the demo down rapidly. Would be a valid reason to simply alternate demolitionists between a mara and a sniper and allow more uptime on the boss for DPS.
Ops Chief - Less time for the turrets to be up = less random, spiky damage for healers. We already have an advantage over most classes in this fight, as we have no setup to do in MM when taking down the turrets.
Styrak - every second buffing add in phase 1 goes down faster, and melee DPS have less need to leave the boss. Would allow me to come out before chained manifestation if nightmared with probably 2 or 3 seconds to spare.
Granted, these only cover PvE bonuses. While I don't ranked PvP regularly, it seems to me that we've been given increased utility and great single target DPS without having to burn our energy to 0 with 2.0. We still have a single ridiculous burst 1v1 (Flashbang, orbital, EP, corrosive dart, ambush, followthrough) that's up every 45 seconds, and we're hard to surprise now with the stealth scan built into our cover. I don't feel that we deserve an upgrade to Laze Target, and I don't feel that there's any way it could be more fairly distributed between the specs aside from making it a 10 second buff to all crit, or something similar.
Put me on the leave it as it is list. I'd rather see changes to make us less easy to play in MM. People are QQing about us for a reason.
