just gonna put up my opinions on the subject, even though I play on ETF2L, hope it doesn't bother my opinions too much
I'll start off by saying ESEA's map pool is near perfection with really upcoming maps in the pool getting updated (sunshine to rc6, metalworks to rc6) with granary being the kind of less liked one with the recent departure of it on ETF2L
for the past 2 seasons we have played logjam and quite frankly it wasn't ready then, and it's not ready now, there is so much work that I just don't think that map is qualified to replace any of the current maps (maybe granary, but even that is a strong question)
ETF2L took out granary the last season and added in sunshine, which was a great decision, some people missed granary without realizing it's one of the only maps that really require work, I mean, check the granary_pro thread, so many suggestions on how to improve it, it's mind blowing, i would say granary_pro needs some more work and testing before really proving to work, i think that the only ones who can really fix the map are Valve but...they probably won't lift a finger to do it.
my question is, what happened to koth_coalplant? i checked the thread the last feedback on it was a year ago with minor stuff to fix, I remember watching games on it and it rather enjoyable, but never knew what was so bad about it
maybe I am a bit biased but I really believe that a map that wasn't given a spotlight yet, with not much testing, is koth_sandstone, I think it deserves a shot atleast some playtesting on it would reveal good or bad.
I don't see any 5cp map currently being able to replace granary other than granary_pro which I'm unsure its ready yet.
edit: totally slipped my mind, seeing that a bunch of people want gpit back, wanted to add that cp_edifice is also being worked on and will be updating to rc1 soon, so maybe a try for a new A/D 3cp map?
sunshine and metalworks are getting updated to rc6 both, some nice improvements, keep that in mind.
logjam isn't ready
granary requires work that maybe granary_pro can fix
what happened to coalplant?
koth_sandstone deserves a shot
cp_edifice (the 3cp A/D map, similar to gpit, made by Phi, the creator of sunshine) is being worked on for rc1
