Besides Ring Wars, Wintermaul TD, and many others, one of the best WC3 (really FT,) custom map tower defenses was pic related, Skibi TD / Skibi's Castle TD It was an excellent co-op TD with little minigames between each round, different armies and more. Fun fact, both its developer and its artist (pic related) got hired by Blizz, which is why it became an "official" map version in later variants.

Both of them, a couple (maybe married later?), working at Blizz had items named after them in WoW. I THINK that this may be one of the earliest versions of the staff she's holding here that was a WoW Priest/caster dungeon model, so this may be where they got the idea for its design! Also

the Rogue dagger, was named after the artist who painted pic related . I forget the item named after the programmer of the map.
