The rules: You can not use other races buffs.
Only dwarfs have SS/sps. (All other items are dropped, but ss/sps is exclusivly used by dwarves.) I think s-grade is craft only, so only dwarves get s grade.
So... lets say 100 vs 100 what race would win and why?
Orcs. With OLs throwing alliance wide CP+HP heals, ally buffs and all that and WCs buffing the parties. Tyrants ripping every archer/healer to shreds and Destroyers taking out other melee classes. And then the OLs would nuke out the other nukers. Ofcourse, every class of the said race should be limited, otherwise it would turn to be pretty ugly. But buff wise, OL+WC can give almost all the buffs that are essentially needed. And they can mass buff so the actual need for buffers is less. 1 OL could buff the whole bunch of 100 thus leaving all the others with MP for some serious healing/nuking.
Oh, btw, just so you know, S-grade is also dropped by raidbosses/big bosses ;)
So, the BH/WS can spam SS, and? They got _no_ buffs, no healers, no nothing. OLs would mass root them, then mass sleep em and then the others could pick one dorfy at a time. Dwarfs would be the last race to win since they got no ranged attacks and no buffers/healers.
I believe the humans would win. Even the history of L2 puts the human race at the top.
But here is my real reasoning. The humans have more specialized classes then anyone. What this allows for them is to be extremely adaptable and versitile. Also they have a great range of buffing and the best healing/rezzing class in the game. No other race could come in and mass rez the 20 or so ppl you just killed in a hard pitched battle. They have strengths to exploit on each of the other races weakness's. Orcs are bit slow and lack the hardcore healing power that humans have and also have NO rezzing abilities what-so-ever. Dark elves do tons of damage and can do it rather quickly, however they can't take alot of damage and are also the most prone to getting stunned. The Elves while being fast and accurate don't have quite the damage output the humans are capable of. The Dwarves lack any support or ranged classes, all the ss in the world won't make up for that weakness.
As for the summoner idea, alot of classes have fear and other skills to help take the summon out of the equation. In the end it would come down to alot of tactics of using the races greatest strengths to overcome their own weaknesses. I honestly think that 4 of the races have almost equal shots at winning if they can use strategies to overcome their enemies strengthes. However, I'm sorry Dwarves, but without support and ranged classes you wouldn't stand a chance. I guess that's why in the history they always went with the strongest side.
OL pulling mass root and mass silence is kinda the killer for those Phantom Summoners. Add in fear and they're good as dead.
For rezzing, orcs can use scrolls as they're sold in shops, and in a battle where the winning team is the one left standing I dont think % rezzes would matter much. HoP+CoL at the same time work some great miracles on tyrants and destroyers ;) And they again heal more than 1 person. In the end, the side running out of MP would most likely lose, and as OL/WCs are the most mp efficient buffers and OL can heal and give cp to them all they can go on longer. Also, nukers would not have bsps so tyrants would go for nuker/healer classes first. Gladiators, DA/Pallys, Warlords, THs... Bring it on, Destroyers take them down since they have more buffs and continuous CP+HP heal from OLs taking turns. Orcs as a race are perhaps the toughest one, fighter classes with 40 str and 47 con as base, mass buffs for the support classes and all classes are really specialized in a way. They really got it all to counter anything any other race can throw at them. So, with good tatics, orcs should have the upper hand.
If you went mostly spellhowlers, then I doubt much anything could survive 100 tempests. With empower, acumen potions, acumen weapons, and cast robes, nothing will match the net damage. It's all about the coordination of the team. Silencing opposing mages and AoE the masses. Sleep the leftovers and it's done.
