Also if you have a crit system, re-rolls (or double rolls and you chose the highest) have a higher chance at crits.

There is also a big difference between re-rolling, and rolling twice.

The examples above with 2d6 vs 1d6 are only accurate if you roll both at the same time.

IF you have to choose to re-roll the dice if you don't like it, that changes things somewhat as you can end up with a lower roll that way (at least for crits).

In 5th edition you have something called rolling with advantage, where you get to roll twice and take the higher (with disadvantage you roll twice and take the lower). This is especially nice for crits, and for builds that have large crit ranges, as it gives you a very high chance of getting a crit hit (even if crits don't do as much as previous versions, just increasing the die rolls for damage, but not doubling strength bonuses and other sources of bonus damage (Feats, rage, magical weapons etc).

Also you need to determine if there are auto-fails (like you automatically fail on a 1, or auto succeed on a 20 etc) as that can alter which is better as well.

In the end, in.....most cases, a double roll (not a re-roll) is better than a bonus to your roll, but again, it depends a ton on the range of the dice, crit/fail factors etc.

To get to an extreme though (DDO is a good example of extremes, at least in the past (now it's been kinda WoW tuned which sucks a bit), you can stack tons of, say defensive mesures to insure enemies don't hit you.

First AC to a level that you would only normally get hit on a 20 (5%), which is the absolute max you can get from straight AC. Then you pump up fortification so you can't be crit at least (even on a 20), then you have 2 types of Dodge abilities (incorporation and flat out dodge) which don't stack but are seperate (each giving you a chance to totally avoid a hit if it actually happens). You can end up with less than a 1% chance to actually take non-AOE damage (and most AoE spells/abilities can be avoided completely with reflex saves + evasion.

Anyway things like attacking with advantage (or forcing enemies to attack with disadvantage) can be huge, especially if you already have a really high chance to hit (bonus), or high AC (so enemies can rarely hit you).

Also initially I thought this said "Hey meth people"...........and yet I still entered (no I don't do meth, but I thought it would be interesting....I am not Heisenburg (but I was a teacher).
