DraGuLa5mbps is plenty fast enough to host 26 people in TF2 WITH my wife and I included. Has happened many of times. Only people with shit connections have lag spikes (never often) Also I pretty much leave most of my Admins alone.
If you think 5mbps is enough to host 26 people, you're mistaken. Save yourself some time and people complaining. Spend a couple dollars on a server. Add me on steam if you need some help :D
Edit: I'll even hook it up with a discount.
