The "Arms Appropriation" prestige mission is mission, where you have to give single 4* or 5* item to gain 180 prestige. Money, which you have to use for it is crazy and theres my suggestion how to fix it.
Let's face the facts:
Nobody completes that mission, because prestige is mostly useless and even if - reward is laugh.
On current state, that mission is obsolete and horribly unbalanced, because example "Monsterous Research" gives 120 prestige.
Single 5* item from depot is 12$ in depot price.
Single 4* item from depot is 5,20$ in depot price.
This is ridiculous price for 180 prestige, which is mostly useless. And reminder: "Monsterous Research" gives 120 prestige. Diffrence in prices is giant.
How to fix it:
For me would be OK if player would have to give those attacked by gremlins knights sets of tier 2 items. For example it would random from 1-3 sets of items needed, which would be for example two Cobalt armors, Helms and two caliburs and one wolver set with cutter.
Rewarding players who already gave 5* and 4* items:
If you have logs of prestige done by players, you could give them 500 prestige for every mission done in past.
What you we gain:
Balanced mission, compatible with lore of that mission and gameplay (npc knights wear tier 2 items, isn't it?), mission able to do by players, who don't farm 24/7, not overpriced and fairly rewarded, use of unused orbs of alchemy and for the most - not obsolete place-taker of other item-give missions.
Since I care about prestige, I can agree that I stopped giving away free items, after they wanted 3* stuff - exspecially after mist energy disappeared and I would have to pay with orbs (even if I wanted to give away more items).
However, I thought, that some people pay for this game and buy their current 5* item needed for that mission, buuut... the current payout is not correct.
I see two possibilities:
1. Stop the star level at a lower number (2-3) or
2. give a higher amount of prestige as reward for 5* items (maybe also another item as reward, but this would be untypically as a prestige mission reward)
side note:
I still wouldn't do this exchange if I could get 5k prestige; but is here anyone who is actually exchanging 5* and 4* items?
