Shield Block Uptime

[Deleted]

I would like to confirm (or not) that Shield Block works as I think it works
Shield Block has 2 charges, each charge has 9s CD starting from when the charge is in effect (not when it's activated), each chanrge lasts 6s. So...

First line: active graph (each dash = 1s)
Second line: cooldown graph (each asterix = 1s)
Numbers represent: skill used(charge used) [so, 4(2) - 4th use of Shield Block, second charge]

    1(1)        2(2)        3(1)        4(2)              5(1)              6(2)             7(1)              8(2)               9(1)

So in fact its uptime is:
- 100% for the first 4 uses (24s),
- 66% for the rest.

Am I correct, or is my logic flawed?

BTW knowing how it works is a big help for bosses like Gara'jal the Spiritbinder HC, where Prot Warrior is an OP

I think from practice, providing you have enough rage you can keep Shield Block up 100% as long as you use them back to back with regular timing.

Where I tend to run into problems is using the second Shield Block charge when my first has like 3 seconds left of the buff, so it jumps to 9 second duration buff, but the next Shield Block starts getting delayed.

A lot of times you just won't have the rage to maintain it perfectly I think.

You were right Kobra. And yes, Gara'Jal rotation is 24 sec SB, Shield Wall+Demo (pool rage and let SB cool down), 24sec of SB again. 1 min of perfect cover each 2. It matches perfectly in that fight.

YES! I knew it, thanks for the confirmation It really explains how to use Shield Block - hope it will be useful for some lost soul.

You can also increase the effective up-time by not using it every CD. Use it before the bosses hit, not in-between hits.
