Many T5u ships have got some nearly useless upgrades to T6 just by having a different name and the only improvement is a BOff additional power.
From a neutral point of view, the upgrade may not be worth it just for that because instead of that extra BOff ability one may just use an additional rep power one.
The only 'it is good for something' scenario I can think of is using the special BOff seats instead of some standard ones, but that rarely is actually useful because if you have a nicely set build it's unlikely to hive up a normal T/E/S ability for a special one.
What are your thoughts on this ? Did you upgrade any of your T5Us to equivalent T6s ? And if so , why ?
