At our last M&G a player brought up that they thought the mana spikes were OP in the grand scheme of the match and the nullification of 240 skill points specific to the stealther template. The player went on to mention that they couldn't use a similar item to nullify a comparative amount of skill points on another template (he used the example of a dexter). I'd be interested in a civil discussion of the merits of reducing the cost of the mana spike and this player's assertion.
