I sent you the replays as pm.
we are gonna try keeper+assassin too, just to see how good is that, but the problem is that we don't really know what keeper should do the entire game exept lowering armor to bosses.
Well at the start you farm the crabs as soon as you can and basically until assa takes over them in her farming route.Then you do all the other support stuff you can do on this map; pull left side, kill the towers on left lane and get things to tp to near gaia/typhos, azazel, drake, farm everything assa dont want, i often end up killing dragons because we ignore them early on (just take a droppped dps item and try how far you can kill them without assa).
Apart from that you generally want to get to lvl 32 as soon as possible, so look to get a lot of xp (also cleverness), and then you want to get your items (broach, decapitator, horn of stampede, chronos).
If you still have some time left go ahead and pull the creeps from the left side of the map to the center forrest or collect gems, or sell all the dropped potions, dunno there's always something you can do ^^
