I think it would be a good idea to make them toggleable. That way you can still only have one but it won't disappear right when you need it most - like how it always does.
Oh please do this. I'm tired of rebuffing skills that should just be permanent toggleable abilities. Warden buffs are only the tip of the iceberg. Knights ( Enhanced Armor, Holy Seal, Crazy Blades), Warriors (Lava/Electrical Attack, Blocking Stance, Battle Creed), Scouts (Frost Arrow, Battle Instinct, Blazing Energy), Rogues (Combat Master, Quickness Aura, Lion's Protection, Searing Light), Mages (M/W buffs, Fire/Wind Arrow, Fang Ritual, Shadow Protection, Messenger or Light, Earth Scepter, Perception, Magic Target), and the list goes on...
You don't really think a permanent HP and 100% + HP and defense buff would unbalance wardens at all?
I agree I hate having to rebuff all the time, and feel that any skill with a cooldown that's less than the duration of the skill may as well be permanent, but in my opinion, the warden pet based skills -should- be like any other pet based skill. (I have two warden/x toons, so don't take that as a 'hate wardens' statement)
Warden's already have an advantage in that they can call their pet, use the skill, dismiss the pet and keep the skill active, none of the other pet classes can, priests can only use their fairy skills while the fairy is out, mage/scout can only use magic cross flow while the flame spirit is out, both lose any advantage as soon as the pet dies or is recalled, it's the same with the egg pets, you only get the bonus while pet is out.
So I feel a making it a permanent buff would give the already potent wardens an unfair advantage.
I'm not sure you understand that Warden pet buffs are for making up for their stat ratios. So making these skills toggleable would be just as fair as upping their normal ratios and removing pets all together. They get the same amount of patk per strength as Knights, less pdef per stamina than a Warrior (not to mention they can't use shields), and less mdef per wisdom than a Scout. These skills are essentially defining their role in a party, you can pick from one of the buffs and fill that role. You can either have normal damage for a dps character, normal pdef for a tank character, or crit (ratio is not enough for it to be worth using). Pets are still in the lame boat, although they can survive much more after the recent hp fix. They barely do much damage, and most skills the Spirit of the Oak and Oak Walker use have a severe delay to them.
