Well, as far as I am concerned, Heroes are thee end all of most problems. Once you get to a point where you have played the game long enough and understand the skill system, spent time playing with builds, and actually using different builds with different Hero combinations, you will own 95% of areas. For many, heroes are considered a game killer as they remove the need in many instances for group human play. Others will say, "thank god for heroes", as they don't have to play with other human cluless idiots they pick up along the way. So, as you progress through GW, you will see how powerful heroes are. A few weeks ago, a friend started a new character in Factions, and we basically did an all-day "run", and with my 3 heroes, the two of us completed the entire campaign in a single day. Believe me, invest time in heroes and builds for heroes, you won't be sorry.
