the problem with those mechanics and incentives is they aren't worth the time investment....
newbie bonus in Sophia ex for example 100 lore I think it is... spend 90 mins wiping only to get timed out with nothing. or soend 15 minutes in a dungeon and be guaranteed 100 lore at the end.....
it might help some what if you got that newbie bonus regardless of outcome.. if you've spent an hour trying to help that newbie only for the group to fall apart you get nothing.. so in the end the incentive just gets lolled at because its worthless...
on a slightly different note though imo what is really unhealthy for the game is the difficulty curve is basically a horizontal line..... players don't get better as they progress through the game. because everything is deliberately easy... and that creats the massive skill gap that exists and that's why people don't want to help newbies... the level of skill you need to unlock zurvan ex for example is a million miles away from the level of skill you need to clear it.. you basically took a stroll along the beach and suddenly been faced with a sheer vertical cliff and the zurvan ex clear is at the top.. that's unhealthy for the game and all it does is frustrate players because either they feel ecluded cos everyone says no bonus. or b players repeatedly get queied with people that have no clue how to play there jobs.....
the game should get harder as you progress. not stay on the same horizontal line.... if it actually got harder as you progressed it'd be like climbing a hill / mountain and not a impossible cliff soo by the time a player cleared zurvan hard. and unlocked zurvan ex he'd already be maybe 3/4 of the way to the summit of actually clearing zurvan extreme. and in this environment you'd probably find players a lot more willing to help newbies. because those newbies are already 3/4 of the way up a hill instead of stood at the bottom of a great big cliff.
but when its a horizontal line. you really cant blame people for not wanting to risk queieng with newbies... would you let a total stranger you passed on the street fix your car just because they want to do it. or would you want some knowledge that they are actually a compentent mechanic before you even consider letting them near it...... if anything is unhealthy for the game its the learning curve
end of rant....
