A pretty poor Tanking set giving you a Tri-Stat glyph equivalent for the 1 piece and for the 2 piece it gives you a little boost of all resources equivalent to approximately 1/4 of a Tri-Stat potion. You could basically heavy attack once on each bar which would take considerably less time and provide you with more resources than this set.
If you perma-block often then for a lot of fights this is going to be ok. The issue is it has a 14 second cooldown, but once the cooldown ends you also need to rebuild the 6 charges. You can gain 1 charge per 0.25 second, In the best-case situation this set is going to proc every 15.5 seconds. That is highly unlikely, however. In add fights or bosses with multiple adds this will be more useful and proc almost on cooldown but on bosses that hit much slower every 2-5 seconds then you could be waiting 45 seconds for this set to give you back quite a small number of resources. Both Engine Guardian and Grundwulf provide much more reliable resource gain, but you need to be casting to benefit from those whereas with Stonekeeper you just need to maintain block.
