Hey, just giving some opinions on what could save this game...

Balancing PVP lockers

PVP Tickets - 90% (9 out of 10 games) of the time, the highest amount of tickets I can earn is 50 in a locker. Usually its 2-5 though from the loose change lockers. Is this really the best you can do? Considering Epics cost 700 for 1 and 10500 for all 5. Do you really expect me to spend $35 currency every time I see that magically 250-500 locker?
****FIX****** Make the loose change locker like 50 tickets, common best reward like 200-300 and 1 out of every 10 have like 1000-1500 tickets as a super best reward.

Materials - give more of the materials. Again, best reward for gold mats are 1? silver is 3-5? that might be 1 upgrade after level 3. Epics upgrading through level 3 start needing 10 silvers and 5 golds at a time, I would hate to see what is level 4 and more. This is what is driving the low mana, common assassin stradegy.
********FIX********** Make silver more common in non best reward lockers, boost best reward lockers up to like 10-15 at a time -- or -- MAke the epics and legendary characters cheapers to upgrade.


PVP Matchmaking

So one thing that makes this game tiny drag, is the forced commitment to your strongest deck. As people are finding out from the first nerf, its quite hard to alter your strategy. As mentioned in the above suggestions, materials are not easy to come by and neither are the 2 currencies required to buy them. Worse yet, lets say your not changing stradegy, you just want to play with new cards. There are at least 2 other thems of untouched materials right! Well, that new deck is still new, yet you have to try it out in legendary rank 3050, against all level 5 cards. Why? Why do I have to take a new deck into that high ranking battle?
*******FIX**********2 PVP systems. 1 still being ranked, 2 being deck power match. So your deck gets rated by its level and matched with a deck similar to that level.

Alliance Trading

Trading epics should be a thing. I think you should be able to trade epic for epic. I have so many pope timmy's and rogue tokens I don't plan on using any time soon, so why can't I trade them for the ones I do use?
