What do you mean? You mean how they beat them in pvp? They get one of the best skills in game at 30 hp, Frenzy which pretty much will take down what they hit in seconds.
I got a lvl 72 destro if u ask me more specific question i'd be glad to answer.
But now to generaliz ,Destro's are a very formidable foe for all non-ranged melee type if played well,they are very dominant in PvP.
In Pve they are considered(hybrid class) as they can tank somewhat good(sumwhat cauz they got no aggro skills)they keep aggro by damage dealt,and as DD well thats there main job IMO they rank up there in the top DD's.
There main weakness are low atk speed&speed,and low M.Def
Destroyers are most valued for being able to open a very large Can-Of-Whoop-***. Frenzy adds like 1k P.Atk (at lvl 1 and just keps getting stronger) for 1-2min.ish with reuse every 10 min.ish. Give them VR+pole and they could rip through entire cata/necro train if all the mobs would even follow you that far. Also puts a severe hurting on RBs and certainly holds aggro for a while.
They can also have the most hp of all classes with tatoos since Orc fighter has most constitution of all races and Destroyer gets Boost HP passive skill that only pole classes get.
Lets see... a highlight, at my clans last Coliseum night consisted of watching the low 60s Destro take on the low 60s SK, the high 60s BH and our high 50s SK at the same time, and win.

since they are nerfing DoF i wont be able to do this anymore, but yesterday i had almost 800 attack speed with a 2-handed sword, and i frequently get 192 run speed from zealot. also, i spent a lot of time into over-enchanting black ore, so i have more m def than a s-grade destroyer in tat jewels +0. all that said, you are exactly right, these are the weaknesses of the class. they have the most hp of any other class in the game however, with a good setup they can make every drop of blood count.
@warraven: frenzy is a multiplier, it doesnt add a static amount.

At level 61 with Infernal Master and lvl 56 Prophet buffs my Patk goes from about 950 to 5500 with Rage and Frenzy. It lasts for 90 seconds and has < 2minutes cool down when I activate the skills holding a Cursed Dagger with SA: Risk Haste [my attack speed is 744 in this state]. This means, in general, that Frenzy is ready to use again before the mobs I just obliterated have respawned and I have knocked my HP back down to 30%. [I guess I need to get a Conversion weapon to help out the HP control now]. What is really annoying is that the skill timer for Zealot is NOT the same as Frenzy [Zealot doesn't last as long and it has a longer cool down]. I have no idea why, and it seems stupid to me.
