I can see your anger with the smite buffs being removed, but to compensate smiting a monster grants a heal similar to smiting red-buff.
Also, lets be honest, people mostly only use the wolf and raptor camp buffs anyway. Wards and sweepers can do the same thing.
Also, why do you hate plants so much when you haven't tried them yet? Riot said if they don;t preform well they'll remove them immediately. so wait for them to come out, try them and if the players don't like them they'll be gone.
EDIT:
Also, the plants aren't solely based on RNG. They can only spawn in certain areas at a definitive time. Plants spawn in waves, near the 15-20 minute mark and onward, and it takes them 30 seconds to grow. The only RNG aspect in them is out of, lets say 3 locations which location will the plant spawn in.
Also, a rioter mentioned that only about 6 plants will be on the map at one given time, which really isn't a lot.
