Perhaps the introduction cooldown on caused by Pets justified innovation, but would like to know what were the reasons for developers by setting so big cooldowns on these subjects that perhaps is equal to their removal from the game. Such a great CD does not give their use even 1 time for bossfight (not the first) – when attempting to kill any complex boss wiping group (actually I can no longer provide adequate situation of their use). 10-15 minutes would be optimal recovery period such items.
