I'm quite disappointed with the rewards. I think DB relies on the competitive nature among guilds as the primary driver to invest without providing any significant, special or custom rewards.
If you look at the top 5 or top 10 rewards, which are going to be achieved by the top guilds / players..
- Guild Rune, ok but nothing any better than a weekly Boss 100 / Honor Shop superior rune
- Icebloom skin, as per Ekko, another skin for a hero who already has a skin - also a hero that is rarely used (I really don't get this two hero skin thing)
- 5 heroic summons, again the same weekly reward
- GT tokens, for those players who don't have 6* these 40-50 tokens are really the only win
Underwhelming for the effort and resources required.
