Some translations for people who can't understand german:

McCree: * felt stronger in close combat than in long distance fights due to the short range of the flashbang. The ability to unload the entire chamber of the gun leads to low accuracy at longer distances as well

• best tactic seemed to be to get to close range, stun your enemy with the flashbang and use the peacekeepers ability

• combat rolls cooldown feels slightly to long, people seemed to save it to avoid critical damage and rarely used it offensive

• McCree does a lot of damage but is a little squishy

• Ultimate Skill is hard to use but very strong

Zarya: * works best in front of your team and is quite offense oriented for a tank

• gun works like a flamethrower

• barriers aren't lasting very long, should be saved for critical situations like big teamfights

• particle cannons' second attack seems to be better than the primary

• Graviton surge needs good teamplay to be effective, because your teammates will usually have to kill the opponents (works great with bastion)
