*disclaimer* please keep in mind this entire post is in my point of view, your mileage may vary. If I seem biased against vanu its because I am, I spent the entire crabpocalypse period fighting them and to make it worse I did so on mattherson, I'm still hung up about it.
I totally understand bro
Main thing I'd disagree with is the odd dislike of the Halberd.
I didn't say it was bad or that I didn't like it. Hell, halberd harassers were awesome back in the day (maybe still are, haven't played harasser enough recently). Its probably the best NS tank secondary in the game, but that doesn't change the fact that every other faction gets at least one ES secondary that is justified in using over the halberd and TR doesn't.
I agree with this.
Halberds are good against both infantry and vehicles and they perform well at long range. Enforcer is better against vehicles if your vehicle is out of cover long enough to empty the magazine, but Halberd is better for popping in and out of cover. With Enforcer you can adjust your aim if your first rocket misses a vehicle and still have 7 or whatever rounds left to pepper them with whereas a halberd would be reloading. On the flip side if you direct hit an infantry with a halberd, he's most likely going to die while the enforcer takes two hits (I think). Halberd also has slightly better splash area if I remember correctly. Halberd is probably better on the harasser because you can fire it, then have the gunner drive behind a hill or something while it reloads, and then emerge again.
As far as TR's ES tank secondaries go, I agree, they were a bit over nerfed. However they were also a bit too strong before the nerfs, notably Vulcans but to a lesser extent the Marauder. The Vulcan just obliderated vehicles and was especially strong on a Harrasser, as at the time Harrassers were absurdly durable what with the better resists than live and the 100% 3rd seat repairs. The Marauder had a tad too much splash damage, that was my main complaint with it.
If you played TR in beta, for a short while the Vulcan was the AI weapon on the Prowler, and it was AWESOME. It had !500! rounds in the magazine. I drove around a prowler and once I sat it in the vehicle corridor in the tech plants and alternated splashing groups of vanu with the main cannons, then while it reloaded switching to secondary and just mowing them down with it. It was a thing of beauty and terror (for them)
I've always thought the prowler could use a chaingun like that again that has a big cof unlike the kobalt but has 500 rapidly firing rounds in the magazine with distant damage dropoff.
