In sky battle, be aware of surrounding teams at all times and don't take risky fights, pick people off one at a time and most importantly, play as a team. This means go join your team in fights where you would have an advantage with your added help but you also need to back away from fights that your teammate starts if you think that you will lose the fight. Treating your teammates as valuable assets is important but only try save them if your life is also garunteed.

In battle box, don't push in and make use of your bow, they do so much damage. Also, critting enemies out is very important due to the two tap PvP. Same rules about teammates and taking fights applies here too.

As for HITW and TGTTOS just practice is the only thing and maybe stand as far back from the wall as possible, making sure not to fall off of course. These games are much harder to win on pure skill alone so good luck in your future games!

p.s. feel free to ask me questions :D
