I forgot that Random battle does not have any relation with PvE, my bad sorry. Well, I got another idea. Since it is Random battle, don't you think reward should also be Random? (The below mentioned rewarding system is just for top 10 Random Ladder players.) For instance,
1st Random Ladder player can get reward a random reward from the options: 2x Reroll ticket / random outfit which worth 250 PvP coins + random item which worth 50 PvP coins / 1x random Jet ski / 300 PvP coins.
Likewise, 2nd Random Ladder player has the options: 1x Reroll ticket + 1x random headwear (excluding champion crown) / 1x random cloak (which worth 250 PvP coins) / 250 PvP coins.
Similarly, 3rd Random Ladder player has the options: 1x Reroll ticket + random item which worth 50 PvP coins / 4x random choice items / 200 PvP coins.
I know all the options can be bought from XXX PvP coins, but just wanted to twist the rewarding system.
The rest 7 players shall be rewarded with PvP coins and berries accordingly. (Don't have anything in mind about the rest players right now)
(If there could be Random ladder tournament every month like Ranked ladder tournament, the top 25 players can also win some cool rewards.)
Also guys, let me know how is my idea?
