I suspect the usefulness of DA has been argued to death in other threads since his introduction to the game.
You could answer my other questions if you wanted...
heh - yes we could...
How are the new heroes? What are they good/bad at?
See discussion in this thread about da. Good at ganks - weak at flag control. Occ is useful some as a tank, but I find to be one of the weaker dgs (several broken skills as others mentioned and some aa bugs).
Are heroes balanced well now? When I quit most heroes except Rook and TB were considered OP
There has been no meaningful balancing of the dgs. The tier 1 dgs are oak, erb, ub. tier 1.5 - rook. and so on.
Any new items?
nope. heart of life got nerfed some time ago so that it is at the artifact shop and costs quite a bit more
Are favor points done sensibly now?
Nope - same system.
How are replays going? Do we need to save locally after each game or are they hosted automatically for us online? Is there a web site where people share great replays? Is the replay editor nice (can easily switch between people and see watch their POV throughout the game, can skip around inside replays, etc.)
Your last game is saved locally automatically, but is overwritten whenever you play a new game. You can save the replays via in game menu immediately after a game, though. There is no automatic replay hosting. Most of us have posted replays at www.gamereplays.org. The replay editor is nice when its doesn't bug out... you can change view from character to character.
Can we mod this yet? New maps, heroes, etc.?
Yes and no. No maps... rudimentary hero modding. You can take existing maps and mod them (adding towers here and there... portals, etc), but there is no map editor - you have to manually find the correct coordinates and plug it in. See modding section of forums. There is a good AI mod called skirmish ai, uberfix - a collection of community bug fixes (it makes occulus work almost exactly as intended - still has the AA bug if I'm not mistaken). There's also favor mod, which uses favor items that excentric dreamed up - alot of fun ideas there.
Can we have more than two teams yet?
Nope. For a different type of game, try out enfos' mod.
Skirmish and Pantheon. I remember one was folded into the other. Are they still alive or are we subsiding on only custom games now?
Skirmish mode was removed. Pantheon is dead. Custom games are it.
And there you go!
