Just my current use of builds i currently run for tyrael

Dive
With tyrael having spell armor now, and his mobility, hes the perfect pick for going against mages. His dive comp basically focuses on having enough sustain that even if youre to dive in and perish the rest of your team would be able to clean up in a team fight. late game with the burning rage and attack speed boost and using your E to close the gap on escaping enemies and nail your Q to completely get back in and wipe them out. even in the worry that chasing them leads to the team ganking you. you still have the damage boost of "Even in death" to kill any squishy assassins that you couldnt kill

Solo with heal

This has way less damage potential in the notion that you have decent DPS on your team that as long as you peel they can survive. with the last ditch effort being your "protection in death" allowing any frontline to lose advantage should they still be in eachothers faces

Experimetal self heal

This is something i've always played with and has had mixed results you have to be very focused on getting the regen master trait as it can make or break this build. so maps you arent strong on globes with it is not recommended. but maps where globes are a plenty. this build thrives. it doesnt come alive until your third talent "follow through" with your E's decent cool down. you have a decent form of getting decent health boost should you hit with your basic attack immediately after hitting with your spells. and your Q works as a "double heal" throwing it gets a proc for follow through, as does the teleport.
with angelic might making this build super important when it comes to getting face to face with another tank the build crescendos to more sustain as you go on. Intelligently using your shields are crucial to doing well with the build. knowing your oponnents bread and butter and mitigating the heaviest damage within their moveset is an important factor in using this build. The times this build works extremely will is when your teammates have a sort of diving comp as well and are in the cut with you as well. you being frontline and your teammates focusing down enemies one at a time while you heal yourself back up from the brink by staying in their face.
