Purple heroes and their war stats

To begin with, I think the new war of heroes mini game is very fun. I enjoy it a lot, and think for the most part you did a great job on it. However, there is one facet that is a serious problem for me, and that is the turn timers for purple heroes. I understand that purple heroes are a bit more powerful but losing the game because your opening hand has nothing but purple heroes in it, is very very frustrating. When this expansion came out I had 14 purple heroes, and 2 blue heroes. I had even stopped checking my taverns because my hero spots were full. But with the purple heroes having an average of a 4 turn entrance counter, I often have my initial hand of heroes contain nothing but 4 turn heroes, and the enemy can often get 2 heroes right up on top of me before I can put anything out. So for the mini war of heroes game, you need a balance of purple heroes and non purple heroes, but for every other aspect of the game, purple heroes are FAR superior. There are two possible fixes I see for this, 1 drastically lower the cost of hero slots. Or find some fix for purple hero timers. Perhaps at level 50, they drop a turn off their summoner timer, and then another at 60. Anyway I see this as a serious drawback for the over all game, when the heroes that are best for the over all game can be a detriment to the minigame.
