I don't mind passionate players tbh.
But when that passion crosses the line, it's a bad thing as his popularity around here does influence the minds of the majority who might be getting the wrong information and impression from him.
His post could've been written in a completely different way and Meddler might've been here to explain the situation instead of also calling him out. And Meddler was right to do so. Because given his line of work (and other Rioters who work on game balance and similar systems), also do get the same treatment from us needlessly. If there's a change we don't like in the game, we should discuss it in a civil manner on the appropriate places, not blatantly hate every Rioter involved in the decision or call for witch hunts.
This only shows how childish and immature we can be and that at some points in time, there's nothing they can do to approach us and explain things without getting bombarded with hate from those kinds of people. It's pretty pathetic that this is sometimes the reality of the situation.
