Trolls/Sea Trolls that have a liability? OMG! That shouldn't be!

While there are plenty of people who seem to think the cost is not worth the effect on Trolls or Sea Trolls, thare are another Category of people who think that with their upkeep they disallow certain strategies (ever notice how well Trolls rebuild castle walls?) and make you take a posture if you wish to use them (offensive). While it may be a little harsh it's still managable.
