U have no idea how to play sps i guess.
First of all,Solar Flare does more damage than Hydro Blast without surrender ON.If someone is using ressist,then BY FAR the best option u have ,is to spam Light Vor + Solar and then hydro.
In 1vs1 SPS ,especially in high x server + customs (reflect shield),u dont use surrender and ALWAYS use vor + solar.
also dont spam in every topic
