Make sure that you have 2 to 5 champions per lane/area, where 2 would be a lane/area you rarely play and 5 be the one you main /rather go/like to go (ask yourself, what happens if
get picked or banned?). Try to keep under 18 champions at all time. So you play less = less champions, you play there more often = more champions. It's really up to you to decide which champion you'd wanna pick. Lets say you're not crazy about ADC, then maybe you should pick "safe champions" to assure your victory and reduce your chances of messing up. On the flip side, if you're crazy about support, then you should be able to cover every aspect and champion type of the lane/area.
Here is what I would recommend you pick since you're a support and mid main:
**TOP: **
-
** Pick one AD bruiser**. Make sure he's a "jack of all trades". He needs to be more of a knowledge based champion (point and click, easy to play, not many skillshots, harder to mess up), then a skill based champion.
-
Pick one AP top. In the event you have an AD mid and you,re forced to go top. Again more knowledge based champ.
MID: You need to cover all aspects of this lane since you main it.
- You must have an assassin
- You must have a mage
- You must have an AD champion.
- You must have an early game champion
- You must have a late game champion
- You must have a "safe pick"
Keep in mind one champion can have 3+ of these things. Remember try to have over 2 for this lane. Max of 5.
**ADC: **
- Safe laner and easy to play ADC.
- There are 3 types of ADCs : regular ADCs, hypercarries and caster type ADCs. Try to have 2 types among your 2 champions.
- For example,
is a hypercarry while
, which is a safe laner, would be your early game harassing regular adc.
- Pick 2.
Support: You main this role, put a greater importance in it.
- You must have a tank support
- You must have pure support (more for supportiveness than tankiness or damage oriented.
is a great example).
- You must have an aggressive support (damage oriented).
- Try to make champion combos with your supports. Like "if my adc goes
I will most likely pick X".
- Max of 5.
Jungle:
- AD bruiser champion that can initiate fights (like
, etc)
- AP tanky champion that can initiate fights. (
etc)
- You don't necessarily need an initiate, but it greatly helps as a jungler. Make sure you at least have one champion with an initiate.
- If possible try to have one early game and one late game.
The general idea is to have a small pool of champs to improve your skills faster.
I hope I helped.
