The old one is more in line with how Shyvana is being played in league. Bland, just like her win rates. The new one is filled with details such as battle damage to her armor, destruction surrounding her, her hands burning so fiercely that you can see strands of melted metal running down from her weapons. It is in my opinion, what Shyvana should be in league. A champion that when you see her picked in ranked you immediately think, "oh shit! why wasn't she banned!?" However that isn't what she is sadly.
Also while almost all the new splash is awesome, there is one thing I hate about it. Her horns. Look at them! They make her head look like a bug's mandibles.
seems to manage pretty well.
