sentinels gets hate because people overhyped them when they won masters and when game was relatively new and in depth game mechanics were not out , at that time Sentinels jumped in game early and became like bullies of the game and people overhyped them then , now as game progressed new things started to vome out , new players began to master there skills and dominating the game now sentinels arent the big bullies of game thats why people who overexpected are hating them
