Please Clarify the New TG Wording

Players assumed that TG made your damage always low, even if using one-handed weapons. The tooltip is intended to clarify that the penalty only kicks in when you have are dual-wielding two-handers.

Sorry for the confusion.

If you are dual-wielding a two-handed weapon, then you pay the damage penalty. You do not need to be dual-wielding two two-handed weapons in order meet that criterion.

However, if you dual-wield a pair of one-handers or you use a one-hander and shield, then you do not pay the TG penalty. In other words, the TG talent does not lower your damage in all situations. It lets you dual-wield two-handed weapons, but at a damage penalty.

I suspect it is the case that if you have a two-hander and a shield that you do not pay the penalty, since that is not dual-wielding. That part I actually don't know for sure.

UPDATE: My suspicion was wrong. The ability actually looks at whether you have a two-handed weapon equipped in one hand and adds the penalty then.

I looked at it this morning, and my suspicion was wrong. I thought the ability might detect dual-wielding but it actually looks for "violating equipping rules" such as equipping a two-handed weapon in one hand. So we can change the tooltip to say something like "While you have a two-handed weapon equipped in one hand, your physical damage done is reduced."

From a technical standpoint, what the ability does is say "You can bypass weapon slot restrictions." This causes the game to not check if you are equipping a two-handed weapon in one hand. It in fact does not even check to see if you are equipping two main hand weapon or two offhand weapons or get the hands swapped. There might be a situation where you want to equip two MH weapons, and the talent will let you do it (but at the normal penalty). I'm not sure it's worth inflating the tooltip so much to say all this.

Sorry if I caused any confusion. I try to answer forum posts in my free time, but I don't have full access to our tools at home. WoW has something like 30,000 spells. I don't know them all by heart. :(

Q u o t e:
This tooltip needs to display the correct information in detail, I don't care if it's two paragraphs long.

We care. The goal is not to communicate every nuance of a spell, especially to new or casual players. The goal of a tooltip is to be both clear and precise. When tooltips get too long, they aren't clear. They are definitely not always easy to write.
