RNG giveth and RNG taketh. Lady Luck holds no favor~
If you are concerned about Detonations and don't want to blow flags on every match, there's a Slot 1 Upgrade which drops Detonation Chance by 70%. It makes a low number a LOT lower and can help you save credits.
Personally, I'd definitely run Det Flags on anything I'm aiming to be competitive in (Clan Battles, Ranked, and Leaderboard Grinds) and Destroyers (because DDs are too important to mess around on).
Outside of that, let Lady Luck's Favor be your guide~
Keep it classy, man. This is pretty bait-y, especially on a post where someone is venting.
The back and forth you two had because of this snipe really didn't help anyone or add to the discussion.
