Hey there!
After playing ATF/CTF for a little bit recently, i feel that most maps could use a bit of a revamp or at least newer weapon placement.
Generally the mode itself isnt that popular, i know, but its still a classic of first person shooters and bringing a few new weapons and layouts to the table would at least help the mod become a little more lively, even if for a little bit.
Here are some things that i can think of so far:
WEAPON VARIETY: Now that we have megaman 9 weapons in the game, i noticed there are alot of older weapons prominent on most maps, and a lack of some utility weapons. For example, theres not many maps that contain scorch wheel from what i seen, which would be a nice weapon to get a speed boost to distract enemies or cap flags faster to push pressure on the enemy team. It seems that most weapons are more so geared to be offensive, with a lack of the more defensive weapons. there aren't many shield weapons availble, and with skull/leaf shield's revamp, it would be a nice weapon to include in CTF for defensive plays.
MAPS AND FUNCTIONALITY: While stock deathmatch maps have pretty neat gimmicks, such as thunder claw and clown orbs to latch and swing across, magic/clown trains, and roadster environmental hazards. While they should be more prominent in vanilla deathmatch maps, it would not hurt to spice up CTF a bit more with some of these (although, i dont think the clownman panels would work out well...). Another thing i feel is that it could benefit off of the newest textures from V4 and V5 to help liven up the maps a little more. Not many of them really utilize that many textures from the newer megaman games because they weren't available at the time.
The layouts do need a bit of rework as well, like icyfort for example: (http://i.imgur.com/CraNkRb.png)
The arena is generally wide open here with the little paths in the river in the middle, which dont allow much room for movement and falling in hampers the flow of the map a little bit. there also isnt much cover out here save for the two cubes in mid and the blocks at either fort.
Another personal gripe is this: (http://i.imgur.com/JScIYs7.png)
Blocks aren't red, its all blue. Just a personal texture gripe but sometimes it throws me off. idunno, maybe im dumb.
And finally the mid section of clash in the city needs some improvement as well. It looks nice but this doesnt flow very well: (http://i.imgur.com/1JZSq0Q.png)
I'd honestly suggest removing the middle pillar, put down two instead with spike pits around them as well. This helps the flow above the surface a bit more while presenting a bit more of a challenge in the underwater section for combat. I'd also recommend making these bars be unable to shoot through the whole length, but still provide some open windows for firing through.
(thanks sonicfam for getting these screenshots btw)
This is just what i generally think so far, and when i get a bit more time, i'd be glad to come up with some potential changes/ideas for a few maps to help improve on CTF.
