Hey these are my suggestions, you said you got my email, but i thought i'd post them here as well :]
Give tower's sight instantly. One way maybe to - instant build , with instant salvage option for 10 seconds only.
Spawn probes in circle at start (just something minor because its hard to move when there is a couple afk guys and you spawn in the middle)
Tree passageways on bottom right/top left - like on the wc3 map where there were larger trees that sort of made a canopy for the ents!
In wc3 you couldnt build in the water! BUT you could build on ramps up to islands.
Make autoturrent smaller so can be placed in between trees easier?? if possible
Scoreboard put all thors down the bottom - just so it is easier to see who is dead or alive when ur are the thors.
STORM EARTH AND FIRE - music enabled
(just something little that is missing from the original, dont have to implement that i suppose as people spammed it and it caused the infernals to lag)
Also I dont know if you removed team killing to stop greivers?? BUT if so, you can still grieve with units like stalkers (can kill probe with summoned unit), so, maybe fix that up too.
+ waterfall!!
obvious ones: items for thors and heroes?, leveling thor skills, greater units for probes to summon.
also i think the line of sight (range) on wards slightly smaller in your version than the wc3 version.
remove fallen trees faster, to avoid confusion.
Provide fallen probes with true sight to detect wards.
EDIT:
- Also if someone builds on top of themselves and there is nowhere for the probe to go they get stuck, unable to issue commands. In wc3 you were moved to the closest available spot (like down a cliff or out of the ring of trees)
