add new level of Friends in need achievement

hi , i see must of Clan users complete the Friends in need achievement and get 250 gems , after that users have no interesting to Donate their friends in clan and they distinction to save their elixir and time

small xp point cant be enough for attraction them

i think it will be great if Supercell add a new level of Friends in need achievement and for example set 500 Gems as prize when user Donate 50000 or 100000 !!

another idea : it will be wonderful if Donate in clan wars Drained and count as Normal donates

it will help to more users participate in donate of clan wars
