Titans always you definitely want at least one COE for the extra two hits. Them titans though, they sexy. ~daT.
Your a little off here. Lets say 1 stat point is worth 1 plunder point Except Defense buildings are 1 stat point is worth 1.05 plunder factor (5% bonus) TOTAL STATS FOR LEVEL 3 ARE: CF = 172,200 stats = 172,200 Plunder point COE = 189,488 stats = 189,488 Plunder point TITAN = 182,352 stats = 191,469.6 Plunder point So Titans are worth only about 1.1% more than CoE in plunder CoE are worth about 9.2% more than CF in plunder and Titans are worth about 10.1% more than CF in plunder.
@Sexwulf You forgot to note that CoE is ".95 plunder factor" as they have -5% plunder on them to compensate for 2 extra hits.
