Its a simple build, but would have a great impact if u dont play it right...

First: U have to avoid to die.. cause redemption loose half charges if u die...
Second: U got to rotate to garantee maximun lane advantage with ignore all distractions.. this talent is also usefull if u kill a minion and them poke, with auto atk, use q or w in heroes and then start all over, kill a minion and poke.. so its going on all the game, causing dmg to heroes and sieging oponnents. than rotate to other lane and do the same.

the build is good with dragonstrike cause its burst oponnets down...
but it can be good if u use dagon strike to, but only in big maps and paper enemy compositions, cause u lack out of dmg without dragonstrike...
