The big difference between Smite and other DOTA games is the greater emphasis on player skill.
This is completely untrue. Abilities in HoN, DOTA and even LoL are much harder to land properly than in Smite. The 3 behemoths of the DOTA genre are more skill based in every way you can think of,
especially in terms of how easy it is to execute an attack or ability properly. In Smite, theres no high ground to take into consideration, next to no stuns, etc.
It's still a lot of fun, but to call it more skill based than pretty much any other DOTA game is a sure way to get laughed out of the house.
As for my personal thoughts on Smite, I like it. It's casual as fuck, and that's why it's good. Rounds are short, abilities are straight forward, items are next to irrelevant since they have no active abilities attached to them. Also, replacing the "ancient" with an actual boss battle is a great idea, it doesn't add much depth but it makes winning a round that bit more satisfying. On top of that you have the V system from Tribes, which is an absolute God send, and something I've sorely missed in every single DOTA game I've played - till now.
On the other hand the graphics absolutely terrible in places, the overall style of the game doesn't really meld, and it's a bit too simple at times. It's no DOTA 2, and that's fine, because it doesn't want to be. I'll enjoy it from time to time, but I can't see it becoming my go-to DOTA.
