Can we not get any items from battling the team leaders? Only been getting Stardust so far...
Right now the only rewards are that and Sinnoh Stone. The most one can get in one battle is 2 bundles of either dust or stones (some people got dust and stone, some got 2 stones). And pray to RNG.
Also, you'll be warned that you can't get items if your bag is full.
Right now, I see from internet, some people just racks wins by multiple accounts or win-trading (never thought to hear that phrase again since Blissey Tower era), since winning or losing gives same amount of (randomised) reward; right now, winning
doesn't give better rewards. Still, I'd rather try my best in excitement, and unlike Raids or other things, there's
no limit to doing it (other than willing friends) for medal progress, and even if one forgo PvP altogether, one can still get chance to grab the Stones from Team Leader battles so eventually one will have too many Stones anyway (unless one got
more Stone consumers like Ryhorn spawning easily), so I'd even skip the battles if I don't feel like doing it. Raids are already enough of a chore....
For the serious players though... I'll have to get used to how dangerous the meta is. With limited availability in each tier, due to limited number of available mon right now, and no intra-tiering and people wanting to just use the most powerful things and how many moves are unbalanced....
Maybe had there be all 'mon already, Xerneas can run over Giratina. Wider selections of mon allow more varied mon usage.
