So far I notice there been a medium reward of troops for stoneheart battlegrounds. As I get higher in the levels the rewards of troops get bigger. Are there going to be tournaments that we can play for stoneheart battlegrounds to win more sketches or as a reward for defeating a quest?

 It would be better to get more sketches as a reward for actual playing(as in winning them then to buy this way we have earn them). The stoneheart so far has been a good improvement for the veterans that have been playing for a long time.
