Because frankly speaking a lot of the GSL protoss players were not as good.
I realise that sounds shallow as an explanation but lets take a look, shall we?
Stats and Classic, both dominant prior to their military service, which Stats is finishing soon, and occasionally debatably herO and sOs, were arguably the best protoss players in GSL.
Trap was very noticably a tier below them in skill as well as strategy - though he definitely had moments of brilliance where he shined, particularly in PvT, alongside Parting who was brilliant but struggled in PvZ comparatively, and after that you had the likes of Creator, Zoun and other names who are arguably tier 2.5/3 protosses who really have done very little of note. Creator specifically, much as I like the guy, really just hasnât been very good historically and struggled to even make it past the Ro16, though recently he seems to have had a once off performace high, much to my disappointment.
Stats is soon to finish military service, Classic has returned from military a while back. Classic has yet to regain his former strength. Creator is Creator, Zoun could be good but needs a lot more work before that, Trap just really hasnât been able to break out of his tier 2 state with some absolutely abysmal performances this year, despite beforming okay last year in foreign tournaments, and sOs and Parting have retired.
With the exception of herO, that leaves us with players who really are not the cream of the crop as far as protoss tactics, micro and macro go, and players who almost never reinvent the wheel the way herO did when he returned, preferring to stick instead to the same style that had been failing them for years rather than try something new.
And donât get me wrong, theyre all good players, far better than any of us ladder and forum plebs, but while theyâre good players, theyâre not great players compared to players like Maru, like Dark, like Rogue, like TY former.
It may seem like a cop out, but in reality, much as I hate to say it, there just hasnât been many good protoss players to take up the mantle until herO stepped into the scene again, and frankly is playing better than he ever has.
