Texture Pack

Recent, my desktop computer is having java problems, which makes it so I cant play minecraft multiplayer. Lately, I have been using my laptop, but its not really the same. whenever I try to play wynncraft, I get massive lag spikes, and its so constant, that it takes me over a minute to walk from the outside of Troms bank to my ender chest. When I logged on to get my daily reward, it took a while for the recourse pack to load. During that time, my game was running very smoothly. So I figured out that the recourse pack is lagging me. and the delay in downloading the recourse pack has happened many times, so it can't be a coincidence. After I figured this out, I went to the multiplayer screen and selected the wynncraft server and then clicked edit. I disabled recourse packs, and re-joined the game. When I try to play, it brings up a message in chat saying that I need the recourse pack to play the game, or else the game wont make sense. I want to know if there is a way you can play wynncraft without the recourse pack. I am a level 51 and I know what everything is by looking at the description of it. I haven't been able to play wynncraft properly in a long time because of the lag. Until I get my computer fixed, I want to be able to play wynncraft again. If you know a way that I can play without the recourse pack then please tell me.
