For the boss token system. Would you say it should be placed for manic dungeons or raids?
Non-raid dungeons should drop only fragments given how the level of difficulty here is much lower than in the case of raids (even though clear times eventually overlap due to the larger number of stages on the side of manics)
Also, dungeon rework? Was there something in KR that was planned to address it?
No there isn't anything planned, that's the point - most dungeons are painfully long, unchallenging and non-rewarding, those craftable rookie raid and grasscover camp sets are useless garbage nobody wants, newbies and loners have access to EC farming only via grutin boxes, THIS IS SO MESSED UP and yet nobody gives a shit.
PS: other core items like Akasha Transmiters, Strength Expansions and Anti-Destructions are STILL being farmed via alts with no high-level farming alternative. Hello? Really?
Hm.. In this case, maybe a rework on loot would be an idea to consider for late content level.
So yes, Energy converter pieces drop in manic of dungeons past level 50 dungeons of manic. (Ruin Fortress and beyond).
Along with those dropping, increase the drop rate of other items to provide more to salvage for things like aethar and so on.
End dungeons on manic beyond 50+ could also provide grutin coin, or a new currency if so be it, to exchange for anti-destructions, strength expansions, costumes, and even akasha transmitters.
This is to encourage the idea that yes, grinding has merit. It can be rewarded for those who actually put grinding in place to earn the currency. This also balances on the idea that yes, Free to Play players can get to where Pay to win players can, but it takes effort. Pay to Win players merely pay for convenience in that regard.
Combining with the bonus key could do well if the loot table happens to get updated to what the feedback post suggests.
Improving on party play could increase the % modifiers given to the party bonus buff, but we could elaborate on that later.
Whales may be annoyed to think of this as a good idea, but if you think about it. The stringent requirements people place for AoV and so on are hard to meet for free to play players, so allowing more ways to get to that gear requirement will allow for more parties to be run and so on.
