We know that warden is more of a "pet" class than Summoner. Warden NEEDS pet to function. Warden's damage is a joke without the pet. You have pet attacks and many rubies require the synergies between you and the pet. We have huge gold in our stock, buy allods gold on our site please.
So on the other hand Summoner which treats pet as a tool and you can change the tool if you want. You can still heal without a Hellion in Allods. You just need to get Blood and heal. Your dps will suffer without Hellion/Fiend but Warden will suffer even more.
And Summoner is currently stuck at level(allods powerleveling) 19 because Concentrated Acid doesn't work with Fiend right now and new Warden is catching up.So you can level Warden higher than Summoner for sure.
Another reason is that we are more of a DPS pet class fan so Warden is a natural for us. Warden is full of controls (mainly knock downs) and attacks. Warden also has decent burst damage in Great Hunt. All you need is to have high rank in Renew and that's about the only team-benefit you can provide. The rest is about you knocking down targets and silencing them and dps at the same time.
