I just realized that Droidster left out the most broken part of the map in his post which definitely needs to be fixed before it is played in ESEA. I'm not sure if you are aware of it already (don't think it was mentioned in this thread) but I have a few screenshots:
You can jump up to this weathervane from the roof below. The medic can also jump on the rocks in the current version of the map if he/she is using the overdose with ubercharge and then jump on the roof and heal the soldier who is on the weathervane.
This is problematic because you can spam (and even kritz!) both second points from either weathervane with almost complete safety from the other team. There are invisible walls which eat some of your rockets, but if you duck you can hit almost anywhere on the platform around the lighthouse.
As a sidenote I absolutely love this map and I have already spent far too long just jumping around it. I am excited that you've made the changes Droidster suggested and I hope with this news some Invite level players will pug the map/provide more feedback to make sure Sunshine can be the best map possible by the time next season rolls around!
