WTii have you tried the standalone version of this game on Steam? This game became so popular they made it into an actually game. So many WC3 mini games become actually games. Ex: DOTA, Element TD, Legion TD, and Line Tower Wars. I'm sure there are other games. It just crazy the amount of great games made on here!
Mr.WTII did you know if you click anti stuck on builder and hover over enemies towers after 10 it'll illuminate them more and make it easy to see their units, so you can decide when best to send against them to counter.
This game isn't as much about unit value as a good balance; if you don't have tanks in front to soak up the damage so your DPS and support can do their work, then you'll lose. Water Elementals are so good in that regard because they're a hybrid - decent HP and decent Damage, so you can spam them in both roles. You, on the other hand, had plenty of DPS but no tanks.
