I have a few small ideas to refresh the Ability Draft game mode.

1.) What if instead of being provided ~4 skills for each of the 10/12 heroes randomed, ALL the skills are completely randomed from all heroes in DotA 2?
2.) Add in base heroes even if their skills can't be added e.g. Earth Spirit / Invoker[??]
3.) Add in 'modified' versions of skills that aren't already in Ability Draft e.g. Rolling Boulder, Sunstrike, Cold Snap, Etc. (4 levels instead of 7)?

Also Shadow Fiends Razes, should be replaced by 'Presence of the Dark Lord'
