For me it's been like that I was a huge trance addict and been for many years and I even grew up listening to techno in the 90's before trance took over and now I almost find trance boring. xD Maybe it changes or it doesn't but I really enjoy hardstyle a lot these days but I agree on the bass loops, that's why I prefer only select hardstyle songs/artists that doesn't loop the bass all over again with a repetitive bass rythm played for 1 min. The newer the hardstyle, the less repetitive bass loopings and the more melodies/vocals etc which some like to refer with this "nu-style" while those refer their preferred hardstyle as "oldstyle" which can be like 1 - 2 mins or a bass loop, then some minimalistic tune or "noise" added to it for 1 min and then back to the bass looping again for 2 mins or whatever. There's a lot of hardstyle tracks I don't enjoy AT ALL, in fact find annoying to listen to, mainly because of the lack of melodies/variety.
Wasted Penguinz in particular as well as quite a few songs from artists like The Pitcher, Butterfly Effectz, Noisecontrollers, Arkaine, Max Enforcer etc. is more varied, more melodies and vocals and varied bass kicks etc which makes it so much interesting for me to listen to coming from an trance background, I even dislike/hate the old hardstyle (say 2004 ~ 2007), it wasn't until 2007-2008 or so when I thought it really got great and seems more and more newcomers have adapted to this change and lots of people have started to prefer it as well so yea it seems like a genre that only becomes more and more interesting the longer you wait (unless you belong to those oldstyle "club"-like hardstyle fans).
Usually a genre evolves into another sub- or totally different genre next to it when enough change in the structure has been made, hardstyle has changed a lot without really have got any specific subgenre (other than this "nu-style" which is too vaguely specified to be actually concidered as a subgenre so far). Trance for example allows such many different interpretations of it why there's all kinds of subgenres beneath it too.
