We should be careful with putting skilling items into the donor store.

No. We shouldn't do it at all.

Firstly GE should be finished first,Before any of these suggestions come ing.

As for the idea, it is a great one. As for the idea bringing more Old-Schools into the game, I disagree.
I think this gift bombing idea should only distribute Donator Rares and Donator Rares alone. The continuous distribution of Old-Schools is a big no no for me.

I think there should be a guaranteed donator rare of 575 or lower DP with every bomb. That way it's still worth something, having 99% skilling supplies is nothing

Also people with 500 DP don't really like to hand shit to others and gain nothing for themselves, they can do that to the people they want and hand out stuff thats worth more than the bomb gives.

I say 1 of the targets is guaranteed the bomber himself, and 4 others. Plus one of the 5 gets a donator rare of 575 or lower. Rest have chances on presents just like you described.

Nonetheless I like the idea a lot

This.
A guaranteed rare should be given out to one of the 5 users, as described in the quote. I think this should be the maximum profit given out by these bombs. I think we should distribute Old-Schools in another way, not in a way where it is just chance to get one.
