well i figure if you are going to make it, I might as well make suggestions:
if bringing back the covert ops class:
- make sniping worthwhile again. 1 headshot kills.
- weaken the sten but get rid of overheating, or at least make it so you can get off half a clip before it does overheat.
- make it so server ops can restrict player classes as well as weapons - thinking of ND80 himself on this one.
- make the smoke have a moderately larger radius.
- lvl 4 CO is worthless, IMO, how about making that the 1 headshot kill.
general:
- bring back the original values for mp40 and thompson.
- another tram map
- another destruction style map. in fact i’d love to see cp games again.
- don’t try to fux with the nade physics again
- bring back the original ET german voice. hearing him say panzerfaust still makes me smile
- although doom3 didn’t have the object interaction level that HL2 has, i’d like to see a more interactive enviroment, at least to the extent that the engine can supply.
- for some reason saving favorite servers only worked like 1 in 5 times for ET. might just be my comp but its very annoying.
- player pushing should be standard not be added thru a mod.
- im a stat whore, I would like to have the game save stats to my machine and be able to see stats for my entire existance under a particular name not just for that round or have to goto a website to check them.
- i miss the venom but can understand why it was removed in ET. would like to see it in singleplayer though
- if you can’t figure out a good way to nerf the meds, consider making the panzer damage area larger again. that will help more than you think.
- playdead, just make sure you can’t exploit it
#13 and most important. do not let this become BF1942. keep it a ground troop battle and not have an insane ammount of free space to run. thats why tram was so great, it was a large map but there wasn’t really any roaming room. keeping everybody in the action.
I’ll add more when i think of some

A better Lv4 solution would be the possibility to carry the weapon of your victim as a dummy to make it much harder to be identified, but you shouldn’t be able to fire that weapon.

comparing to blizzard community, ET one is poor. Add some more userfriendly features.
