I also didn't know about the spellbane bug at the time. I just thought he forgot to have it up. It wasn't like I fought ragers all that much to notice it was a real issue.
What you also don't see from this one snippet of my character, is the times Kelkezi busted my ass. If you notice, I also have A/B/S up when fighting Garfuka 1v1. You think it's me being conservative, or the fact that I've had my ass handed to me by Garfuka too many times not to take him seriously?
Try to use your rational mind, sometimes, and realize that these logs DO NOT show the entirety of any character. They are brief snippets out of over 500 total hours.
Having said that, I recognize I play a little more conservative than some (although the game seems to be trending towards UBER CONSERVATIVISM). But saying an invoker shouldn't fight a RBW with A/B/S is just stupid.
