I'm not sure I see the point of a SRT rogue; stealth, sleight of hand, ranged weapons and initiative are DEX. Why do you want a rogue with high AC but low stealth and SoH? High AC also often means disadvantage on stealth due to armor. Seems like you would be better off with a straight martial class if you want high AC and straight up damage.

Not to say a rogue has to dump strength, but I'd still want a high DEX and CON before putting to many points into STR. Unless you're going Arcane Trickster, which seems pointless with all the scrolls in the game, INT, WIS, and CHA could all be dumped giving a rogue good DEX, CON, and STR.

Am I missing something?
