I'm very much a fence straddler on this issue. I very much love the increased challenge of issue 2. I've grown somewhat bored with the mission process on the live servers because they are just too easy. However, I don't think that one hero should take on hoards of even leveled opponents either. As it currently stands 1 hero is supposed = 3 even minions = 1 even lt + 2 even minions = 1 even boss. We all know this is not true at higher levels, and to be honest I don't want it to be true. I agree much more with a previous poster who suggested...
lvls 1-11: 1 hero = 3 even minions = 1 even lt & 2 even minions = 1 even boss
lvls 12-21: 1 hero = 5 even minions = 1 even lt & 3 even minions = 1 even boss & 2 even minons
or
lvls 12-21: 1 hero = 3 +1 minions = 1 +1 lt & 1 +1 minion = 1 +1 boss
lvls 22-40: 1 hero = 7 even minions = 2 even lt & 3 even minions = 1 even bosses & 4 even minons
or
lvls 22-40: 1 hero = 5 +1 minions = 1 +1 lt & 3 +1 minion = 1 +1 boss & 2 +1 minions
or
lvls 22-40: 1 hero = 3 +2 minions = 1 +2 lt & 1 +2 minion = 1 +2 boss
lvls 41-50: 1 hero = 9 even minions = 2 even lt & 5 even minions = 2 even bosses & 3 even minons
or
lvls 41-50: 1 hero = 7 +1 minions = 2 +1 lt & 3 +1 minion = 1 +1 boss & 4 +1 minions
or
lvls 41-50: 1 hero = 5 +2 minions = 1 +2 lt & 3 +2 minion = 1 +2 boss & 2 +2 minions
or
lvls 41-50: 1 hero = 3 +3 minions = 1 +3 lt & 1 +3 minion = 1 +3 boss
Now to talk about Statesman's argument that this would create a spawn for 8 lvl 41+people of 72 minions. First off, if if they code to eliminate the 9 minion option and instead use a minimum combination of 2 lt's and 3 minions, you won't have that problem. Second you can create code that only allows a 2 step shift on the scaling. Thus at level 41-50 you will not see mission spawns less than +1. Mind you this would still creat e the possibility of 56 minions, so maybe the minimum spawn would be 1 lt and 5 minons, to reduce that spawn to 48. This even spawn would also be a pretty rare case with most spawns being at the 3 minion = 1 hero spawn scale or 5 minions = 1 hero spawn. The larger 7 = 1 scale should only be used to create the epic Heroes versus an army feel. It is my opinion, that this situation would make missions remain solable, but also scale them up to create hazard zone conditions when you bring in a full group.
