Still in b1?
Cmon I played that map 6 months before...
Anyways, I dont think the gameplay works too play. Its a TFC map after all and 1:1 copies of tfc maps just dont work for TF2.
2fort fails
warpath fails
and now avanti fails as well. (Yes I know, well is a tfc map too, but since it wasnt only converted from ctf to cp but _also_ has made significant design changes its a good map

)
The map isnt even beautiful. It looks like a CS 1.6 map.
I wouldnt play it regularly.
Wait. 2fort doesn't fail because it's a TFC map, but simply because people rather stay in their base and make it an impregnable fortress (haha, 2fort - fortress, what a pun

) instead of attacking the enemy. So, this is mainly a CTF and not a TFC problem. Go on a server with any CTF map running: At least half of the team will have garrisoned inside their base (mostly as engis or snipers). Thus, if only 3 or 4 people in a team of 12 players try to get into the enemy base, grab the intel and get it to their base, it's not suprising that they fail, since these 3 or 4 people can't really cope with about 6 or 7 defenders + sentries.
You will see this problem on Turbine, on 2fort, CTF Well and on any random CTF map.
