I've mentioned it a few times, but Bole did have it's little niche, granted that it was indeed very little and very very niche
My favourite example is A12S, I entirely solo healed the add phase and getting a bole allowed my warrior to not putting up tank stance for their add. Whilst it's fair to say that it wasn't particularly optimal play once you start factoring in combined DPS, it helped my Warrior's DPS a healthy amount and was enough to net my co healer the highest DPS by a SCH in A12S by a healthy margin at the time, enough so that it was only ever beaten by literally 2.2 DPS.
The card had potential IMHO and if SE had looked at allowing ASTs some way of countering the RNG, perhaps at a cost of GCDs I think it could have opened up more uses for the card, especially with it being as strong as it was and tank stances working the way they did back then.
I suspect it's a bit moot now though, with the way things are now it'd likely only ever find value as a way to abuse or skip a mechanic.
