How many rubies would you have available?
Also I'd suggest to go and play league subscription server if you are a new or returning player.
Why you'd ask?
I understand many of you say that you have invested xxxxx euros in this account.
This is exactly why,
Don't be a slave of your own money.
What you spend is spent, it don't matter when or where or how much.
If you have spend sooo much as you'd claim and still complain about getting 2shot in pvp bg's and underperform in pve compared to others, despite the CS you have available,
then go play on the league subscription server where a better game waits. The population is currently lower but if every returning player goes there instead of wasting their time for 2 weeks on f2p only to end up complaining on forums about getting 2 shot and not able to do anything because "CS", then that server will be fixed in no time and everything will be much better, for everyone!
