I'm glad i'm not the only one that thinks they need to do something about the old box set. I wish I can convert my old cards, from old box set into gems. It's sad having cards that never going to be meta anytime soon.
How about this:
1) Reduce gem cost for older box during events like how that had the 3packs+1UR deal. Maybe half price for older boxes and for a limited time only.
2) As for gaining 5 gems for each win, no that's not a smart choice. People will just abuse this system.
1. Option to buy gems with coins (ex. 100gems = 50000).
2. Using keys to upgrade cards to prismatic/glossy (could be only for Legendary Duelist rewards based on their color)
3. Sell solo cards for gems (ex. 1 UR = 1000 gems)
4. Make better rank-up & cumulative rewards to motivate players continue playing.
5. Add better cards to Ranked Tickets
Also make battles on gate multiple.like now with normal foe to have more then 1 battle for example for 10 and if they not give us more reward to make it much better
Or it will be great to make auto battle play alone more battle for example to set auto battle to make 10 battles without us keep tapping if we are bussy or make a comand for set a time interval for battle.for a 1hour or more
I propose that ultra rare and super rare cards from older boxes be but into events. maybe 3, 4 or 5 ultra rare and super rare cards per event. i'm sure people would like to see cost down, neo deadulus, the creator etc as rewards. rather them than the cheap, useless wannabee farm cards they give us.
