Finally got some testing time in.
Sniper Changes
Seems like a generally positive change. In combat, I didn't find that it changes very much. Your snipe just becomes a heavy 4th blast, which I was used to as a Devices user, but without the risk of losing a blast you might have gotten used to because someone threw a dark blast at you. As a Blaster I have enough attacks in my rotation that I didn't notice my snipe having a longer recharge. From the perspective of Beam Rifle, I have Disintegrate management eating up enough time that the recharge doesn't matter, and I imagine other sets have similar concerns.
The out-of-combat sniper shot hits pretty hard, but I could almost live without it. Testing at level 50, enemy resistances tend to blunt the impact quite a bit unless you juice it up with Aim/Build-Up/Surveillance/etc. It's basically good for deleting one boss Stalker-style. Was that the intent here, to mimic Stalkers?
All in all, seems like a modest buff, but nothing that really breaks the game. Just a tweak upwards in DPS for the most part. I'm not really seeing what's making people complain.
Devices changes
The damage on Web Grenade doesn't matter to me much because I've rarely used the tier 1 immobilize on any Blaster. It will be extremely welcome for low level Blasters though, before you have a functional attack routine.
Taser becomes a melee attack, and that's cool. Actually, there's some great synergy here with Caltrops. Again, it's of more value to lower level players, but it's a nice hard-hitter that's a bit longer than melee range to wreck up people stuck on your Caltrops. Even at higher levels, 4 slots in Taser will give you something to fall back on when you've sucked down slow debuffs.
Targetting Drone gets recharge reduction, which isn't quite what I was hoping for, but I'll take it. Given Time Bomb's extended recharge, to say nothing of Gun Drone and the thematically linked LRM Launcher, it's a pretty nice benny.
The change to Time Bomb feels team oriented. It's still going to get used the same way: Throw Smoke Grenade, drop bomb, start fight. This will just annoy teams far less now that they don't have to wait 10 friggin' seconds for you to deploy the thing. Now it seems like Trip Mine is the skippable explosive, with Time Bomb being the vastly more usable alternative.
If I could talk you guys into a quick deploy for Trip Mines, I'd be pleased as punch, but Devices feels pretty good amongst all the other power creep now.
P.S. Change Field Operative to not permanently turn the user into a ghost, please. Blasters have to run it all the time now, and I'd like to be able to see myself in combat. Maybe get the low-pitched hum to fade out like other toggles, while you're at it.
