I suppose this deserves a serious answer from me.
First of all, I'm going to fully admit that I have a vested interest in both of these things. I own Titan Industries, a Tier VI company that along with ATC could very likely hop right into Tier VII. I also own Astraeus Industrial and Kuhn Consolidated, two Tier III Companies that are both poised to jump to Tier IV. With that being said, I'm going to say that this makes me more apprehensive.
Tier Advancement:
To address making company growth more difficult, I'm going to say right off the bat that the Tier expansion of I->II->III->IV will never become more difficult than it currently is. I'm a huge proponent of more people getting into the game of companies, and I do not like the thought of small companies having a hard time growing into a Tier IV company. I view Tier IV companies as basically starting to step into the galaxy and gaining influence. I believe most things, if not all, can be accomplished with a Tier IV company.
Expansion to Tier V and then to VI signifies to me that a Tier IV company expands away from its original design and purposes and becomes something larger than itself. I would equate this to Monsanto or GE, companies that started out with a single purpose but now own a little bit of every single pie. This further expansion in my opinion would require further development. If I were to make it more difficult to raise to these Tiers it would not be about major faction contracts or miscellaneous threads. It would be about acquiring Subsidiaries, contracts with smaller entities( Lower Tier Corporations and Minor Factions), and expanding to new locations.
Tier 7:
I cannot lie and say that my heart does not desire this, but I will ask one simple question.
Why?
What could I possibly do at Tier VII that I can't do at Tier VI? The way I see it right now this would be little more than a way to wave my e-peen around and say I have one of the few Tier VII's. The only tangible bonus would be that corporate fleets become larger. That's it. Thats the only benefit as far as I'm aware.
So for those of you who desperately want Tier VII to happen, here are some questions I'd like answered first.
1. What would Tier VII accomplish for your corporation?
2. What can't you do now that you could do under Tier VII?
3. What in your mind is the difference between Tier VI and VII?
4. What would the Tier Expansion look like?
5. How much are you willing to pay me?
