What about each of the pets?
Like does some recharge MP? And I remember one of the horseys has wind strike or something like that

Mew the cat, storm cubic and one of the ponies can shoot "wind strike".
Again Kat the cat and one of the ponies can recharge mp.
The buffer pony can give mprecharge buff too.

PS is the best shadow with vr nightshade with a rly big heal and curse gloom\hex mass and single Phantom Summoner forever

look dude lets talk about PS my favourite.PS have the best cubics of all summoners just think phantom cubic = hex deacrease patk atk speed that mean on pve u are the best and the best cubic EVER spark cubic = its not stun its shock that mean you can stun easly a orc fighter with majestic on him this shock depends on Mdef and btw on dex some ppl forget the jewels ex: ppl over 61 have C or maiby B grade....and summons Best pve (catacombs) its Shadow he have pasive Vampiric and that mean u will heal him next year .....NightShade its like a bishop believe me when u first time learn Nightshade he heal with 800hp i think anyway its the best PT summon and btw this NightShade have mass hex/mass gloom and hes better for both pt mages and fighters pt........this is some advantage now lets talk about disadvantage summons speed are low so with an archer or mages in pvp u are dead (lets not forget about sleep u sleep the enemy and go near him and shock him and kill him PS have a rly big Int 44 and curses will land no problem) thats it i recommend for u PS because hes the best solo (sry for my english )

and to know summoners are the hardest char to play just to know a summoner never rest

PS is my choice... but it is the weakest summoner in fact there is almost no use for you in any party - mages like elementals more, fighters like cats... Nightshade is nice with healing, but you still need another healer to be effective fulltime - Nightshade's HP go veeery fast down, esp. if he uses also the hate/debuff skills. The VR of Shadow is really nice when you solo, but you don't have to heal any summon if it is properly buffed, and Shadow eats a lot of exp. Soulless is great summon, nice speed, good patack... but you need a recharger with you to do anything but sitting behind. It's nice effect for RP, but it makes PS disadvantaged compared to the other summoners.

Phantom summoner is the best Hexer ever.
How can you say it's useless to any party?

And Stun IS THE SAME THING that Shock.
And WHERE did you see that Dex influences in resist it?

...

i say on dex romania the l2 server not dexterity some ppl say i will buy a wep and armor and jw later and PS shock depends on Mdef

PS is perfect to fighter parties. It is awesome.
But i choose warlock, because cats rule the world xD

Warlock is nice because of binding cubic and feline queen is welcome in any fighter parties.
I don't think Warlock is better, than PS i just love Warlock much more.

ES is created for mage parties mainly, but it can be nice with a warlord in pve. (I hate elves more than ever since Merrow The Unicorn got empower acumen clarity and WM buffs in T2)

What dyes should I use on warlock and what dyes on PS?

For ps I would definietly go for +4wit, +4con, +4dex. Same for warlock. For ES if you still got just C-grade wep and you want your curse land, you might give +4wit -4men.

I'd invest in at least sov acumen for a summoner.
If not som acu. I'd always carry a soes btb after me.
