Combos are categorized into 2 types.
1. How easy is it able to be carry out in game?
2. Are the combo good in lane controls or good in clashes?
Firstly, if u wanted black hole, epic and freezing field, root and
echoslam etc etc. It is extremely difficult to carry out. It maybe
be very good but in game, its hard to carry out. So there's no
point choosing such heroes that their combos are hard to carry
out.
Lane control types. If u were to pick lane control heroes. Take
note that they mus be able to contain enemy right from level 1. If
not, its gg already.
Clashes. Good combos could help u win clashes even if your skills
are not as good as your opponents.
My prefered combos.
QoP, Zeus, Sandking, BB, POTM.
Why?
Zeus wif sandking. Opponent dun even dare to touch creep. Risk of
being stunned and zap. If u dont know how pain, i assure u its very
painful. Red life immediately. So u have the upperhand in lane
control. 1 stunner 1 nuker.
BB wif Potm. BB, thick life and spray are good nukes at the start.
BB could farm despite being a melee because of its spray. With Potm
a range hero covering BB, whats more need to be said? Starfall and
spray enough to kill whole lane's creep. Potm's arrow should be
able to hit target. 100% dead meat for that fella who got stunned
by the arrow should be dead if he got the hit from the spray and
starfall. Even he survived the stun time, the goo from BB to slow
him down is enough. His ally? Consecutive sprays from BB while
wacking the target is enough to kill the target's ally even his
ally was not even being aimed at. another win from lane
control.
QoP? solo mid of coz. High chance this qop will be tamed by viper
or warlock in mid. Therefore, heroes from top and bottom after
dominating in their lanes should run mid to help qop. QoP should
not run lanes if it was tamed. If it was able to own mid lane. Then
running top or bot is no prob.
Sandking and Potm are lane runners. Zeus qop and bb are
farmers.
Zeus should get his aghanim by lvl 14. If u use arc to farm. Qop a
preser,boots, 1 orb by 14.
Sandking should have dagger by lv 12.
Just to say i've won 4 games in this combo and haf yet to
lose.
Its not easy to get what u want in drafts. So choose heroes that
could work well almost in any combo.
