Giant Growth elixirs, well largely depends, if someone is playing an orc/ogre hybrid, I'd see it as a requirement to use giant growth elixir. If it's your average worgen or whatever, I'd question it but largely not bother with it as it'd be quite hypocritical for me to condemn as I have RP'ed very tall humans for a long time now, though I don't use giant growth to show that off anymore. Largely I personally think it useless to show off your character's height by use of a growth elixir, unless they're exceptionally tall. Like if a human is let's say 230 cm or taller, I'd think it odd if they didn't use giant growth, but even at 200-210 I'd see it as a waste to use giant growth. Though it's just my opinion.
