2H and s/b tanks - defence/dps comparison
Posted: Tue Jun 07, 2016 1:39 am
I've seen people posting stuff implying that s/b tanks have much better survivability than 2H tanks. These posts seem to imply that the 2H tank gains nothing worthwhile from dropping their shield and taking up a 2-hander. So I'd like to provide a comparison of balanced builds for a 2h tank and s/b tank based on the evasion stats that the shield supplements.
The comparison is made for level 40 toons. The tanks are assumed to have 300 weapon skill, 230 initiative, and 100 willpower, 1H weapon dps value of 51 (best scen weapon currently available), block rating on shield = 357, 2H weapon dps = 74.
Formulas used in the following calculations are:
Block% = 20% x block rating / attacker's main stat
Parry% = 7.5% x weapon skill / attacker's strength stat
Dodge% = 7.5% x initiative / attacker's ballistic skill stat
Disrupt% = 7.5% x willpower / attacker's intelligence stat
Block% against Guard damage = 20% x block rating / 350
Parry% against Guard damage = 7.5% x weapon skill / 350
Combination of Block and Parry/Dodge/Disrupt against hits = (1 - (1-block%)(1-parry/dodge/disrupt%)) x 100%
The attacker's main stat of str/int/bal is assumed to be 800.
For an s/b tank, base evasion stats will be:
Block% = 8.9%
Block% against Guard damage = 20.4%
Parry% = 2.8%
Parry% against Guard damage = 6.4%
Dodge% = 2.1%
Disrupt% = 0.9%
Combined block/parry against frontal melee attacks = 11.4%
Combined block/dodge against frontal ranged attacks = 10.8%
Combined block/disrupt against frontal ranged magic attacks = 9.7%
Combined block/parry against Guard damage = 24.6%
For a 2H tank, base evasion stats will be:
Parry% = 2.8%
Dodge% = 2.1%
Disrupt% = 0.9%
Parry against Guard damage = 6.4%
So at this point, the s/b tank obviously has better evasion stats. So I'm going to spend 40 renown points on improving the 2H tanks evasion stats so that they match or surpass the s/b's stats. 20 points spent on each of Reflexes and Deft Defender will give the 2H an extra 18% in parry, dodge, and disrupt. So their new stats will be:
For a 2H tank, boosted evasion stats will be:
Parry% = 20.8%
Dodge% = 20.1%
Disrupt% = 18.9%
Parry against Guard damage = 24.4%
Comparing these stats to the s/b tank's stats listed above, it can be seen that the 2H stats have now easily surpassed the s/b tank's stats.
So the s/b tank now needs extra defence to match the 2H's evasion stats. But they also need extra strength to match the 2H extra dps that was gained by equipping the 2H weapon. This extra dps is 74-51=23 points of weapon dps. This is equivalent to 115 points of strength when contributing to ability damage and 230 points of strength when contributing auto-attack damage. Overall, the s/b tank would need about 140 extra strength to match the extra weapon dps (also taking into account improved chance to bypass target's evasion stats). Spending 34 renown points on Might will give the s/b tank an extra 120 strength. this leaves it a bit short, but it will have to do.
Spending 34 renown points on strength leaves only 6 renown points for improving their evasion stats to match the 2H's boosted stats. Let's give them 4 bonus points so that they can buy the first 3 levels of Defender. This would give them an extra 6% Block. So the s/b tank's new evasion stats will be:
For an s/b tank, boosted evasion stats will be:
Block% = 14.9%
Block% against Guard damage = 26.4%
Parry% = 2.8%
Parry% against Guard damage = 6.4%
Dodge% = 2.1%
Disrupt% = 0.9%
Combined block/parry against frontal melee attacks = 17.3%
Combined block/dodge against frontal ranged attacks = 16.7%
Combined block/disrupt against frontal ranged magic attacks = 15.7%
Combined block/parry against Guard damage = 31.1%
Comparing the boosted stats of the s/b and 2H tanks, you can see that for builds balanced between dps and evasion, the s/b and 2H tank are fairly closely matched. The s/b tank takes less Guard damage but it receives more damage from all other sources. The dps capabilities of both tanks would be fairly well matched.
You can re-do the calculations for different combinations of stats and renown abilities, but the comparison doesn't really change. Choosing a shield doesn't automatically provide better survivability on its own if you want to match the 2H's dps. Any benefit of one choice over the other is going to come down to the abilities and tactics you choose to complement your dps and evasion stats, not from the stats themselves.
