Very impressive project
But how much does your whole project cost at the end ?
Well total cost is:
5x WoW EU Vanilla accounts for5x€5,00 so
€25,00 (special 5-year anniversary deal at wow-europe.com and some stores. I used my main-account so only had to buy 4 vanilla keys...)
1x HB RaF License for
€39,99.
+ electricity and computer uptime (depreciation on computer parts)
+ maintenance (training every 10 levels)
+ 1000 gold for all 5 characters skillups/mounts/glyphs to lvl 60 (can be estimated at
€6,00 but correct me if I'm wrong)
What I get out of it is:
- 60 mage and 60 warlock on my main account
- 4 more lvl 60 characters on my main account thanks to granted levels by RaF's (8 RaFs, 4 mages and 4 warlocks), which is a total of 6x60 on my main account.
- 20 euros for each of the 4 RaF-accounts (containing a 60 mage and 60 warlock) when I sell them (so
€80,00 total)
- 4 free months of gametime on my main account (when people activate their subscription on the RaF-account) which is worth about
€56,00 total in my country.
- 4 free Zevhra mounts on my main account (which is
priceless 
)
In my oppinion, well-worth the dough.
I hope this was an answer to your question.
