/chuckle.. not that we have many left to link. Guess he could link SE line.. but who actually casts multiple versions? Only time I've ever done it was when I was buffing a much lower level toon and was trying to find the version that would stick to em.
If they linked IoS to the focus buffs, I'd be annoyed, cuz I'd have to wait another 10 secs or so to finish buffing the pet. I could honestly see the true pet runes being linked (kk.. lets hope these get missed then), as long as the Spellbreaker's line is not linked to it. Other'n dots, there's little else to link.
If he wanted to piss off the entirety of the shm/bst/necro world and make em all leave the game in total disgust, he could look at linking the dots, which he hasn't fully done yet... but I think it wouldn't pass review, since for us, they are such a relatively insignificant portion of dps and usefullness.
