while it sounds amazing, I do wonder about the strategy as it's a 5v5.
If I've read it correctly, it seems that this mode is relatively similar to the arathi basin battleground in wow, which is a 15v15 map. But because AB is a 15v15, there can be multiple small skirmishes breaking out at the capture points. I wonder if this will occur as nicely here, because if everyone on the team is attacking a defending a base, and all bases are engaged, (which they very well might be given stealth and the like) then it will be a number of 1v1s across the map. 5 1v1s to be precise.
I suppose it could be intriguing to have to completely change strategy if they have a vlad and a jax, but when I first read the map, I assumed it would be a 7v7 8v8 10v10 etc.
At first glance it seems that everyone would want to spread out 1 per base, and that even though someone could 2v1 a base, that it wouldnt be that important because of the low death timers, with that person coming back and making it a 2v2. Having them dead for a bit could be good, but where's that 6th person to assault the nexus?
Although admittedly, all the possibilities of speculation might be a positive sign.
