i play dota a lot and am not such a big fan of HoN. i feel that there is weak game balance, a needlessly complex UI, and they dumbed the game down through the removal of animation frames for attacking and casting
i like to compare the removal of animation frames to versus fighting games like street fighter, tekken, super smash bros, etc. imagine if a weak jab and power smash both animated instantly and took the same amount of time to activate. the game would be reduced to one move that trumps all others because you remove the depth of timing and reaction. HoN is alike in that respect, the instant animations removes the gameplay depth of timing, animation cancelling, movement, and unit collision and reduces it to "right click attack"
Totally respect your opinion, I know a lot of people who still prefer DoTA over HoN. But there are a couple wrong facts, and trust me I play both.
The UI is very complex + large, however, you can customize it now with add-ons. Removes pointless UI art blocking your view and so forth.
Also, I'm not sure where you got the idea of "instant animations."
All units have attack animations that are NOT instant, and can be canceled using S or H depending. Also, there are cast time animations that can be interrupted and canceled.
In case you don't believe me, there is an item known as Behemoth's Heart (remake of Heart of Tarrasque) that when equipped by any Intel hero provides them with a 15% reduction in cast time animation. Why would they have that if all animations were instant?
Honestly they've taken all of the things that make DoTA a fun and competitive game and fixed the problems.
-Rated accounts that record wins/losses + kills/deaths
-If you leave a game pre-maturely it will affect your standings and prevent you from joining certain games
-3 minute reconnection window if your comp crashes or have a internet connectivity issue.
-Stand-alone servers so that if they host d/c's the game continues as normal.
Way more stuff, but just wanted you to know about the animations and stuff, no idea where you heard that from, no one would play this game if that were the case.
