Variations on a theme. We've looked at stacked stuns and items, now let's think on Demigods for a moment. What happens when you stack the same ability from multiple DGs?
One example (from an IRC convo with Gazpar and Mcmjon, thanks guys):
At full range and skill Regulus can snipe for a little less than 1000 dmg. 5 Regs on a team means almost 5k focused damage from one ability with a low cooldown and extreme range. An organized team of level 15 Regs could hypothetically destroy one enemy DG every 10 seconds until they ran out of mana pots.
Or what about Mines? At level 15 Regulus can produce 12 mines with high slow and damage properties and low cooldown. 5 Regulus players on a team could throw out 60 mines in about a minute. 6-8 maxed mines will kill most DGs.
Please note, I'm picking on Regulus only because he's the DG I'm most familiar with. I'm not calling to nerf him at all. I'm sure you could extrapolate any DG's abilities the same way. TB's fireball, Rook's Hammerslam, UB's Life Drain, etc.
So the conclusion I'm reaching is that few elements of the game at this point have been balanced in multiples. I'm sure that won't hold at release, but some potential solutions in this case:
1. Make 'each team may have only one of each DG' mandatory in tournament leagues where teams are organized. Limiting it to two each per team might be a more flexible approach in this vein.
2. Give stacked abilities diminishing returns, so the first snipe gets full damage, second snipe gets 70% damage, and dropping off steeply from there. This would be useful in the case of all other currently bent mechanics like stuns and favor items.
