Hey OP, i'm not sure if you're an admin or someone related to hosting this event, but I've been trying to contact someone regarding the Starladder Online Qualifiers (date). If you do have someway of contacting them, let them know regarding the issue below.
Is it possible to move the Starladder Online Qualifiers for after the 2nd of May? Because many teams will want to participate in the Manila Majors Open Qualifiers, which will be held from the 29th of April until the 2nd of May.
Both of these tournaments are a big deal, i'm sure it would be more beneficial to move it to the 3rd of May as it wouldn't clash with it.
