Of the classes and weapons that were modified in GPP, the Lucifer Cannon has the #2 worst set of modifications. (#1 is the goon. Kudos to Unvanquished developers to restoring the chomp to its rightful place as the most powerful attack!) I propose to scrap the gpp changes to the Lucifer Cannon and make it like the 1.1 luci instead.
The gpp luci is faster, but the old one is actually more useful overall, as well as a more interesting and unique weapon. The biggest reason is that gpp luci stinks at killing dretches. It's not right that the humans' most expensive primary weapon is probably the worst of all of them for killing these nuisances. With luci 1.1's higher splash damage it was typical to blow up several dretches with every shot. The gpp luci is stronger for going 1-on-1 with a goon or rant, but to me this does not seem the true purpose of this weapon. It makes more sense for the luci to be used with support from some chainsuits or whatever (though I probably spent the majority of the game in many 1.1 battles trying to sneak into aliens base alone with a luci...) Anyway, a skilled goon/rant should still be able to avoid getting hit, so clearing dretch clouds is a more important function.
The gpp luci is too similar to the pulse rifle. They have fairly similar speeds unlike the slow 1.1 luci balls. The way to minimize damage against both is to wait for the human to reload/recharge. With the 1.1 luci, charging was faster, so the play involved more of dodging the luci shots after they were fired.
Finally, I will discuss my most favorite part of all about using the 1.1 luci: blaster switching! This is definitely a feature, not a bug. This is what I miss the most about the game when playing humans on gpp. I have itemtoggle blaster bound to a button on the side of my mouse, so whenever the luci 1.1 was charged up and no alien was near, the charge could be canceled by pressing this button a couple of times. (If you didn't have any of these buttons you could use right click.) The 1.1 luci had a lot of ammo, so the maximum ammo could be reduced quite a bit due to this ammo-conserving feature. This would be nice since it would encourage people to reduce their random shots all over the place which bleed teammates. Blaster-toggling is just totally awesome, what can I say...
