Strats added in 1.9:
-correct use of shield while fighting
-bow boosting with levitation arrow (to mid, for example)
-food supply: eat the right food at the right moment, for example: you are at 10 hearts, you eat bread. You are at 3 hearts, you eat steak for faster regen.
-correct use of arrows (use the right arrow are the right time)
:)
These aren't any strats. Shields are close to useless, you can block player hits and arrows with it. And if you don't have it up. You still get hit. (And it takes about a second to ready up.)
Levitation arrows, not sure if you've ever played factions on a big server. But levitation arrows are about the same as a punch bow. You hit yourself and you fly off. So that has been in the game for ages now.
The food supply, no one cares about what you eat, when you eat. Everyone just eats. Steak does give you more saturation, but that doesn't mean bread will heal you a lot either way.
And about the use of different arrows, the spectral arrows show you the enemy. Total uses? Non.
Levitation arrows, so you will shoot your enemy in the air. And then you'll try and hit him again? So he will be on a different island, because otherwise he will fly back on the island.
1.9 didn't add any strats that weren't already in 1.7/1.8.
All the added things aren't making up for new strats.
