I did extensive testing of Skill Masteries when they came out with ToL, and posted the results.
So, i've been testing various skill masteries on TC 1, and posting my results on the News thread about Publish 90. I thought it would be a good idea to post the results in a dedicated thread, one not littered with complaints about gold or castles/keeps. Here it is. First of all, you must have...

I will be posting the results of my Skill Mastery testing here for the Masteries that have changed since Part 1. Skill Mastery Testing All tests were done with Lvl 3 Mastery. Mastery abilities that trigger while hitting a victim, no longer trigger during a Weapon Special (so no combining...

I definitely need to re-do those though and post a more up-to-date thread on them, now that much more is known about Skill Masteries.
For PvM though, between Fencing Mastery and Parry Mastery, Fencing is more useful.
FENCING
Thrust is a sustained Toggle, and when it is toggled with Lvl 3 Fencing Mastery, your auto attacks will deal +18% damage and reduce your victim's attack damage by 18% for 8 seconds. Both the damage bonus for yourself and the damage debuff to your victim stacks with successive hits, up to +54% damage for yourself, and -50% damage for victim, however successive hits do not refresh the duration. It costs 30 Mana (subject to LMC) to toggle Thrust, and each successful hit landed during Thrust consumes 30 Mana (subject to LMC) to strengthen the buff/debuff. Thrust can be toggled without cooldown, and lasts until either you un-toggle it, or run out of Mana while attacking. The -Damage debuff to victims does not stack with the effects of Feint. Attacks during Thrust cannot exceed 35 damage in PvP.
"Pierce" with 120 Fencing/120 Tactics does about 40-50% of the victim's max Stamina in Stamina damage over 10 secs in PvP. Against players with low max Stamina, they can potentially out-regenerate the Stam damage. In PvM, Pierce seems to almost always damage 40% of the victim's max Stamina over 10 secs, even monsters that have massive Stamina, such as Anlorvaglem (1,100 DEX/Stam, so 400+ Stam damage in 10 seconds). Three Pierces is enough to drop most creatures to 0 Stamina. Pierce struggles though to lower the Stamina of creatures with Paragon level regen. It requires constant upkeep of Pierce on them to lower their Stamina, and if Pierces falls off of them for even 5 seconds, they can quickly regain their Stamina.
