So I just had an epic idea (solution?) to all our "problems" in raids, here goes:
Make an item at the beginning of every instance you can interact with once after entering the instance (like there is for CM on every boss), this item sets your status to "inactively participating" and you can only turn it off by leaving the instance and rejoining again. If you are set to this status you can participate in beating the boss, like everyone else, but you won't count towards the maximum player limit (10), that can usually enter the instance and actively participate. You don't get loot or achievements either- nothing. If 10 players are in an instance the 11th can join as soon as at least one of the 10 sets his status to inactive- this way you can't trick the system into having more than 10 active players that get loot.
this will lead to:
in my opinion this would be an easy to implement solution (but i'm actually no IT-specialist, so maybe i'm wrong here). The only thing this would not implement would be hardmode, but that is already covered by CM or lowmans i guess, if that isn't hard enough try solo (or maybe 49 open world players and you?)
I hope A-Net reads this, otherwise every opinion is welcomed, even if you want to accuse me of crying for easymode (wich it is not, I do raid regularly and have 300+ LI)
The only kills i'm missing is Dhuum and W6 completely due to a long break and therefore not having a static at the moment, so the training thingy would definitely benefit me, yes. But I'd definitely have fun helping out in bosses I already did my kill in the week in a big zerg, or letting inexperienced ppl join in bosses I do know already.
