Just because you land the Mark/Dash spell, doesn't mean you go in 1v5 and keep dying!

Seriously? This new summoner spell is forcing lots of stupid losses because people just go right in after landing the Mark/Dash spell. Its ridiculous. If you play like this please stop, its not fun when you keep dying and we can't fight the whole game because you just go in 1v5 after landing the spell. How would one address this issue ;-;
