Was thinking of a few new pets that would be useful throughout lvling your character. Like the brown wolf lvl required 20 price 80k gold and glowing spider (white walkerling) lvl 60 price 600k gold and for some ppl that shouts out for the rat the dmg dex and arm is not far between the green spider lvl 120 and bat 250 so how about the lvl required for rat to be around 175/180 price 3mil gold and for the challanges with us bigger players with a dragon how about a dinosauris lvl required 580 or so price 25mil gold. See how many agrees I can get on this by players including mods/admins/staff team then let's see what our honourable game creator can agree to for the fellow contributioners.
I agree that there should be more pets in different level ranges. As far as price/monster I don't have much input, but there is a big gap between level 40 grey troll/45 war dog and level 120 green spider. From there, the gap is still large to the next pet, but a level 120 character and 250 character can generally get to the same areas for grinding and what not. Pets just don't match the character's abilities. I know that pets can't be as strong as their owner, but they generally can't survive anywhere the player needs to go to grind.
