This game may be D&D rules but not it's spirit. If combat was this difficult in D&D nobody would make it past level 1.
This. Most of the combat encounters seem to be designed by some DM that has never played or DM'd before. A bunch of archers on high ground and throwing bombs at you, creating surfaces and blast dmg that seems to avoid your AC, on top of lighting u on fire without rolling a dex save.
