No, the blaster was wicked lame. Lower DPS than any other weapon in the game, and it made it way harder to make a getaway if you ended up outgunned (which, since you're using the blaster, is wicked easy). Only thing I ever used it for was taking out exposed solar panels.
The laser rifle was pretty awful too, since moving after a shot is an important sniping tactic, and bloody necessary if that shot is a giant red line pointing to your exact position. Even with an energy pack it was tough to move with it, and trying to take on heavies with it was suicide. Plus the 'instantaneous' bit only helped LPBs. Those of us with >100 ping still had to lead.
Tribes was usually about quick, highly mobile strikes, which made having your most basic weapon steal power from your jetpack kind of lame. Although the shocklance in T2 still ended up being awesome, mostly because you could make a stupidly quick kill and still have enough juice to get away (provided you were smarter than the average bot... which some people never were).
I'd have to say the worst I've ever been stuck with was the fists in Dark Forces. I remember at the start of one level being stripped of all my weapons and dropped in a pit with I think 2 kell dragons and my fists. That's no kind of fair. They were especially disappointing after I'd gotten a few tastes of Doom. I had seen the chainsaw... and there could be no comparison.
After that, maybe the knife from Op For. I mean, you got the pipe wrench... which was no crowbar, but still pretty sweet... and then the combat knife. Sure it was fast... but the pipe wrench. Come on, 1-hit-kill on virtually anything you can reach with it, vs. the paper-cut machine.
The bizarre flip side of course, was that I ended up using the combat knife to open boxes and the pipe wrench for combat. Based on Op For, our government should re-equip all of our ground with $15 wrenches, because the $50 combat knives just don't get the job done. And then the barnacle gun? Ok, so I know it ended up useful as a game mechanic with the grapple, but I still ended up disappointed by its weakness as a weapon.
