LFG for 5e d&d game. Tired of games ending because the dm cant handle above level 5.

I have been playing for a while now. tired of joining games that the DM doesnt know how 5e works or just end it because the dm cant handdle the game above level 5. I am an well versed in 5e and the rules set. So if you have a space for a solid mechanical player please drop me a line, my time zone is utc +1

You have played from one to above level 5? Lucky...

What happens at level 5 that breaks so many dms?

level 5 and 11 and 16 are changing points in the game, no more single attack monsters and stuff. players abilities also get way pumped. Dm try to go in with the same mind set as pre 5th and dont know how to balance fights

It is the first jump in power, with the extra attacks and extra damage on cantrips/spells that PCs get. I only have done it with Princes of the Apocalypse, so the balance was kind of written in.

true 5th level made many a gm quit because player charaters where getting to powerful and thay like it not worth gm anymore because monsters been getting owned had a group of all level 1s take out a 500 hp monster sunday nets and low roles by gm under 10 with +4 to streangth was crazy he had rolls total of 7 or under 3 rounds then net again after break out first and 2 more rounds of hitting 5 players vs 1 npc ac 14  Barbarion double hand axe attacks every turn ranger  2 attacks short swords a cleric spell and mace hit 2 times a warlock casting and anouther spell caster we defeted the npc champion half giant champ in 6 rounds with hits after hits and bad rolls for gm.
