The same people that complains about Malzahar also hates Heimerdinger, Yorick, Zyra and pets.
In any games MMO, Moba, the Summoners Class are always the most HATED. Why? Well you expect a fair 1 vs 1 but then there's a 3rd party called the Pets comes in and gang on you. Although Summoners Class are primary PVE and excel at PVE bringing them into a PVP can makes some Salt inducing players.
Comments I've receive while playing Heimerdinger: Wow this Donger is soo bad hiding behinds your turrets like a tard. You only killed me because you had turrets.
Although Summoner are very fun to play and probably the funniest to play because of how much salt it creates to player. And that is why we Love playing the summoners. Just to be the Jerkiest Jerk in the world.
Why I play Summoner champions? Simple, you know when you have unreliable teamates and you wish to carry them, you sometimes wonder if there is a champion who can do it. How do I replace my teamates? That question was easely answered when I held Donger in my hands. Turrets= Players Turrets= More reliable than your teamates Turrets= Listen to you and many more. Playing a summoner class is liking playing Pokemon or an RTS.
