ive recently read a bunch of discussion on these issues, but the solutions proposed seem either silly, or the ravings of someone who loves 1.1 too much.
before i get to what i think is the proper course of action, let me just say that i think dodge is bullshit, and rant charge needs to be fixed so that jumping does not negate its damage. i wish jumping made me immune to the bulk of a luciball's damage.
now, what i have read is that pounce is overpowered, charge is overpowered, rifle is too good against dretch, and dodge is bullshit. i disagree with the first two points, but agree with the last. aliens, as a whole, only have four attacks that can possibly oneshot a nekked. goon and rant attacks. just as i was told to evolve to basi to avoid MD/SG oneshots, i tell these players to buy larmor.
to avoid instant death from charge, jump like everyone else does. charge does not need to be changed, as if it was, the aliens would then have no way to clear congested halls. it is bad enough to be forced to wait for s3.
so, the solution:
give the alien classes damage reduction. "light" and "heavy" for sure, and perhaps "medium" and "structure" as well. then you make the human weapons more or less effective on those armor types, based on the purpose of the weapon.
light armor is not really what you would expect. it offers no protection at all against light weapons. on the other hand, heavy weapons are far less effective against these targets. rifles, shotguns, chainguns, and flamers would likely be the most effective against light armored targets. the targets with light armor would likely be dretch, basi, basi+, granger, granger+, and mara (if not using medium class armor)
heavy armor would be the opposite of light armor. it protects more against "light" weapons, but heavy weapons are unaffected by the reduction. massdrivers, prifles, lasguns, and of course the luci would be the heavy weapons. mara+ goon, goon+, and rant would posses heavy armor.
(option) medium armor would be a bastard armor class. you could give it to basi+, granger+, and mara. effectikve weapons against it could be shotgun, flamer, lasgun, and prifle.
(option) structure armor is harder than hard armor. it gives extreme protection against "light" class weapons, but is very vulnerable to "heavy" weapons.
of note: i did not include grenade or painsaw in any list. they are special cases and could be said to ignore any armor. i believe this could be balanced as the psaw must be in melee range, and the nade is a one use thing.
now, you may be asking yourself, "how does this armor shit make any difference to the topic?" well, to tell you the truth, it does not in a hard and fast manner. what it does is encourage more variety in human weapon selection. it introduces an Achilles' heel to the larger aliens, and hopefully promotes more variety in class selection. more variety means less goons and rants. less goons and rants means less pounce and charge whoring. then we can talk about how OP basigrab and grangerspit is.
but, this does do jack dick about rifle vs dretch. so how about giving dretch a lunge. basically, a copy of human dodge, only it lacks a backwards use and has a forward use.
