Struggling to scrape any enjoyable BG together, looking to trade this in hope to get something to build a BG out of.
Which one is cheapest will depend on which theme you go with rather than which faction. Most of SL relies on a few legendary or exotic champs in each theme so I don't think it would necessarily be cheap. SP tends to be the cheapest faction since fewer people play it. If you want to stay with SL, what theme are you wanting to play? (themes I know of for SL are arthropod/myx, sand, dragons, skeezick, draksar, and fire/acid)
Sand primary but im starting to understand that sand is a sub theme rather than a complete theme based on the sl forums, so im thinking of sand core with maybe fillers to provide aoe/range. going to try to watch some sl players and get an idea of what I will need.
If you're planning on doing a sand-heavy build, I'd recommend spicing it up with some insects/arthropods, as the two themes complement each other quite well
Could you be so kind as to list a few runes that I might need I really dont know what champs spells relics and equips i will need
This isn't anywhere close to ideal, but it should give you something to at least start with. Keep your Thorn Collection and see if you can trade it for a better champ or two (Krikkinwing Alpha would be a good choice or maybe Skywing Imperator) https://www.poxnora.com/trader/viewtrade.do?id=3773823
Just bid a token or a common you're not going to use. When you get a chance, and can afford to, pay it forward.
