whats more unfun to you a counterpick or a one trick or finally a "toxic" champ

examples ( or one trick or just plained countered where your useless in lane or game ) basically anyone you cant basically play the game if you do you get punished for it in lane if you die to them they become stupid strong and carry the game in some unfair 'i couldnt do anything anyway' way. (oh i forget people report you for feeding or not helping if thats the case)
