Should they anyway go with the freeze-scene at the end of a match, could they please freeze all objects (karma, instant hit graphics, other weaponfire). I did sometimes do that with "playersonly" command, and sometimes i got some real cool screenshots...
Could they stop removing weapons? Make a list of "official weapons for this release", who is redone, and is the weapons mainly used for this game. But (as with a few of the weapons and actors in U1 -> UT) let the other weapons, unchanged or changed if they got the time, be accesable to mappers.
Not split the character selection into races, but teams.
Make it possible to, in a botmatch, to select whole teams. Like when playing CTF 4vs4, i select that Thundercrash should be my team (i will be assigned 3 random bots from Thundercrash), and the enemy is the Necris Blade Maiden (4 random bots from them).
Let most weapons do more damage. Play with the UTClassic mutator from time to time, it IS more fun.
Keep the minigun, but tweak it a bit more. In UT i always prefered the minigun before the 'link-gun'. It felt like they did the same damage, but it was easier to keep the gun on target, and it felt like the victim became slowed done a bit.
Add a few custom deathanimation before the ragdolldeath hits. Like the 'standing and shaking' while hit by a minigun and dies, or when your head is missing, while the body didnt get much momentum, let him stand and try to "feel his head" before falling over.
Not every time, of course. Let there be a bit randomness, and a few conditions that has to happen...
Limit the translocator even more (most players probably going to disagree with this).
Of course; four teams! Not necessarly any maps, but supported by the gametypes and the skins (like UT99). And that i say without ever having played it four teams...Just liked to give my character the green skin in DM.
I missed the local UTStats. Using OLStats when playing in UT2004, and enjoy life 4.2% more
.
When playing onslaught, i want to be able to get home again when i have lost my vehicle by a deserted, but closed node. Maybe having an translocator always stationed at the homebase? Or make vehicle lockpickable? I dont care, i just want HOME!
Make a long jump actually dangerous. I dont have count on how many times i have taken no damage from a jump from Torlan tower.
Make shields at 100 the default shields, while shields at 50 an xtrathing on a map. Like in UT.
Make the pickups better looking. A rotating holosymbol just dont look as cool as an actually medkit to pick up. Same with big shields (armor) and small shields (pads). Again, maybe make them optional for the mapper (classic style/modern style).
Which leads to my next point; more for the mappers...even if its never used officially ingame, include it.
One of my other ideas in another post: able to do a few new dodges when ducking.
Last: What is it they did with the perspective in UT200X that made every look and screenshot feel "wrong". I just never seem to find the right FOV...
A bit longer post than i planned, one idea just seemed to remind me of another idea i have had...
