How can you make more on pvp than normal EB's? You might get more per hit but finishing bonuses for EB's can be huge. I can make 20-30bil a day on EB's, with just pvp you will be lucky to make 10bil because of pot and mith costs probably less.
No support. For you, someone who is likely not even LLBC with T4, upgrading may be easy on small Ebs. Try upgrading a 150-200b building off normal haunts. Ain't nobody got time for that. Normally I'm anti-eb. I love war and for a longtime I never grew. Since the last alliance war ended I've decided to grow all my accounts to help clean bigger strips for next war. So taking out HTE would severely hurt my growth which will leave me in the same tier of farming mid sized accounts and only being able to get through steals on accounts with little spy defense
