Focus doesn't do anything either. Just dodge if you need that focus block so badly. The DPS gain from the explosion is really tiny too. By the comparison the on-demand block from the shield pretty much shuts down half of the boss mechanics in the game, which is also the reason why guardians are so popular in general.
I still think that the easy vuln stacking, regen application, condition removal, and an on-demand 3x block/DPS burst is better than shield. Don't misunderstand, I use my shield on specific fights where necessary, but I still like the utility that focus provides more.
ANYWAYS, getting the thread a bit off-topic.
Just get a GS, tbh.
