Grand Chase and Elsword

Alright, so recently KC under KOG has acquired the old server data and now is currently hosting both Elsword and Grand Chase.

Can someone give me a gist, without just using Elwiki to pass me the general niche and quirks of Grand Chase. Like anything in particular that would be interesting or worthwhile trying on that game in your experience. If you have played Elsword, then you can use Elsword to Grand Chase comparison with your opinion on the differences you noticed or little things like mechanics and stuff that you found interesting.

With that said, I'm just wanting to hear some opinions and experience between the two games if you have played both of them. If not, then just your opinion Grand Chase on the following items:

• Story line or plot (Anything worth noting)
• Fluid Mechanics and Input scaling
• Animation and Graphics
• Pets and what they can do for you (generic info)
• Costumes (If you have played Elsword, then you just tell me the difference)
• Characters (Are they memorable) and their classes (just want to know if it similar or generic to Elsword)

Yes, I'm somewhat aware that people has mentioned that Grand Chase came out before Elsword. So perhaps the graphics doesn't match up or compare to Elsword. But I'm still interested to hear opinions on the game regardless.
