Friend in need of help
Hello all, I've been playing this game for 3 years now. I have a friend who started maybe a year ago, took a few months off from the game for a bit and then just returned this week. He mains the ADC role with Sivir and Jinx being his champions of choice to play as. He does fine when he is able to get the ADC role but that almost never happens in PvP games. He isn't that experienced in the other roles so I have been giving him some examples of champions he can learn to play those roles.
What champions do you guys suggest a beginner player picks up that can play Top, Mid, Support or Jungle? Please be mindful that my friend is not level 30 yet and is saving up for runes still. So if you can pick champions who are relatively cheap to buy or can fill multiple of the aforementioned roles that would be great.
ashe is cheap, has recently had her kit reworked and is a great champ to have in your stable... learning to last hit and position when you have no implicit escape
amumu can fill many roles, good price, good kit, good team fighter, a great champ to learn how to jg or tank and when to back off from a fight... or initiate
nunu- i dont always care for him but he has point n click abilitys, can go into many roles, and teaches about short range threats
annie - powerful, able to be used mult roles, fun, good to learn as a burst mage, or an ap support ( or even a top lane, stuns = escapes)
morg- yes please.... on so many lvs, yes pls... a lane pushing champ, stuns-4-dayz, support, team fight, and teaches you to learn and manage your cool downs
sion- great champ, strong, tanky, can fail at farming and still make great impact, teaches a lot about ability interactions and combos
because she is the music in the silence, the yin to the adc yang, squishy, 1 shotted, but unkillable.... she will teach you positioning and patience with adc's, as well as proper utilization of complicated ability interaction when played skillfully, and can spam abilitys until skill is obtained
