And any heroes that i sould give attention if i were to get them (im f2p)
Orksbane2003 is right to point out you use 2 healers and there is no need for that. I would go with Druid, however. Unless your Ork is way better developed than Druid, he is....quite mediocre.
If the heroes you listed are the only ones you have, then focus on WL, PK, Pixie and Treant, in this order more or less. Throw in GR somewhere in the mix, as well.
Immo is a great substitiute for Vlad (I am assuming you don't have Vlad) but the moment you get him, dump Immo. By the way, for anything other than HBM I would substitute Immo for WL.
Honestly by looking at your heroes i thought you were in mid game as everyone in late game has awesome heroes. For lost realm the best team would be PD, Cupid, PK, CK, Druid and Pixie/ GR. Gr for everything in lost realm except deflect demon and reducing damage demon. Pixie can remove the shied from deflect demon so you her in place of Grizzly. PD and Cupid are buffers and PK and Ck will help reduce energy
Aries is 1 of the best heroes if you give him 5/5 revite so lvl that one up but don't replace anyone untill he is 7-8/10 and around same lvl as your mains. Then you get there I would use pd,cupid,druid,santa,immo and aries.
While I agree with some above, there have been some mentioning ck over wl. WL is way more important in so many modes. Sniping (him and pixie are 2 of the best with aries being there as well) and are critical to GW (which is very important due to fame), exp, raids. Focus on those.
As for dracax, so far, most are not finding a good use for him, but that may change.
