*Currently, the game is very hard for newer players?*
==> I don't think its hard for newer players, If I take exemple from thebaythe and snow; they begin the game this summer at august they started normally, they asked how to play ... We told them that there is ton's of tutorials online so that's what they do they have been exping to the xmas dungeon which they found the existence from a FAQ (yeah FAQs are also here to help people), they both completed their task.. they both reached 110 in less than 2 weeks, and reached 107 phys in 1 month. For items they crafted many things like ninja wand and those new items from xmas dungeon they also told me that they got some cool items like ancaria glove from the chest at xmas! But they disapear from graal now, for a unknown reason.
An other exemple is Zach he won with less than 14 hours of playing a ring of descending darkness but he fast lose it even I told him like 10 times to save it! But someone bought it from him for nothing!
LIKE me

I have won a rare con +2 belt worths probably more than 2 rows, well because I didn't knew the price I traded it to fenix for 4-5 basic tigables

*I would really like to see a comeback in the pet system,*
==> For the pet system people will probably think that there is already a pet system but that is too old for you..
But you probably means that you want to create a pet doing like you said ingame healing people or attack people in pvp?
Well I can tell you that this is a born to die idea! Why? Because you will need someone that doesn't work for gk but is free to help and that can: GFX ,and then make all the sprites (which is really long took me 1 day), and then make a gani, and finally script it. Even if someone can do that he couldn't test it on GK , his onliest possibility is to go on a playerworld and ask a rc for test even he does accept you.. Yeah but you going to tell me what about the dev team? Well they have tons of works and that is too long to do.. so that's what it's a born to die Idea.
