Exactly, we should be working on offense. Expert rings do not benefit a defensive linker unless they are trying to bolt while being hit, which is not a very smart idea because it messes up your resurrection. They would be purely for augmenting the bolting and stave crashing ability of linkers. Also, linker's ability to endlessly stay alive does not work in lms, tlms, or anything of that sort, so no one uses them in events like that. Perhaps if this was implemented they might see at least a bit more usage. There is also the fact to point out that even with full gear and 300 int linkers will still have 6k or less matk than profs, while profs get double bolt as well, so linker bolts would not be severely overpowered.
