I have only about 2 hours in the game, so this could just be early game difficulty.
I could be alone in this, and honestly historical have never been a fan of explosion type enemies but normal difficulty has way too many explosion enemies, to the point where I get surrounded by self bombers and grenades and die instantly when doing quest/side quest.
I would understand more if this was in hard mode. Though maybe the problem is more so readability as I have a hard time hearing the war cries of the self bomber and find it difficult to located the source of explosion in mid combat, and end up moving around more like a headless chicken, and trying to running from grenades and end up running into self bombers.
Edit to clarify something after rereading 1 last time: It's more so that It feels like I'm being punished for playing both slow, and fast paced. If I'm slow, then grenades are hitting me left and right, and when fast I feel like I'm more often running into bombers.
For some idea's so I'm not just complaining:
-Toning down the Self Bombers and introduce a "brute" variant of the Skeleton.
-Reduce damage and radius of explosions by 5-10% (though the problem is more so the amount then difficulty because they aren't hard to kill)
-Honestly an Indicator that an enemy is behind you or about to attack could help as it's hard to hear them do their war cry when crowded, or when quest/ side quest noise is happening. though again that could be on me as I do have a habit of listening to my own music/ having background audio playing.
