I dont quite agree on the bold statement.

If need 150 / 220 gold for ward or upgrade courier fast , can last hit few creeps?

If supporters aren't allow to last hit creep , then where to fund the money for supporting?

Get few creeps are allowed.But if last hitting every single creep on lane , then it is the supporter's fault already.

And , why cant carry bring some dust / ward themselves in certain situation? It is just 150 gold for observer ward only.15 gold more than your TP.

dun ajaran sesat sia ns lvl up ulti is really good especially early night
coz the night will be much more longer
lvl 1 silent for 1st night is enough already if u gank harder 1st night can reach lvl 11
thats mean u can have extend the night much more longer
who no up ulti ns early is really wasted
