Useful tips 'n tricks

Hello guys ! I started this topic because I am stucked in diamond 5 (and you may help me with tips & tricks) and also because I want to help you with some cool facts that may be useful sometimes. So if you have any tips or tricks related to gameplay, I'd be glad to hear them. I'll begin : _- vladimir's ultimate buffs itself

• vladimir crimson rush duration decreases slower if he is in zhonya's / W
• as draven, you can catch enemy draven's axes
• don't use flash and then a point and click ability, use the ability first and then flash for instantly effect (same at some skillshots)
• as Ryze, you can use Zhonya R for unstoppable escape
• in teamfights, you can put random wards in front of the enemy adc. If he's not using right click for aa, he may focus sometimes the ward
• Braum E can protect an adc from Lulu Polymorph
• Don't unlock ultimate instantly at 6 as Blitz, unlock it only when you want to use it
• if Zilean put the bomb on you, try ro denny enemy adc farm
• You can use an ability and then fast upgrade it for reduced mana cost and same damage/effect (ofc this applies at projectiles)_

I tried to give you some less known facts. Any other tips ? :D Btw, sorry for my england. (Jk) But really now, sorry for my bad english.
