Bring Back Lower Mobility Champions

Whenever I watch LCS games, I notice that most of the champions that are picked are high mobility champions, like , , , and . I feel like this is really limiting the champion pool and restricting some of the less played champions like and . I feel like all these champions would suddenly become viable if mobillity became less important, making these players pay more attention to their picks and consider counter picks that aren't necessarily highly mobile. Does anybody have any thoughts on how high mobility has become one of the most important factors when selecting a champion? As a former(pre-dfg removal) main, i understand how mobility and responding in time is important (because i have none), but should it really be important enough to stop the pros from ever playing a champion?
