This is a very good RA3 map. I only ever got the opportunity though to duel on the CA map on FragLove (even though I think it's too big, but I let my opponent decide hehe) but all the arenas seem to be well-constructed and have good flow. Using CTF maps as a base was a great idea and it's pulled off flawlessly. The CA reminds me a lot of Theatre of Pain, a bit curvier but has the same kind of open atria you'd see in ra3map1a4. Would love to see that map with items in it for FFA! If you have a FL account and like open maps, give it a go.
