PR can only realistically 'shield' the top two slots on the party list, yes, and not forever, as the Scottish example demonstrates with its historic decimation of the Tories, LDs, and now Labour. Compared to FPTP, the upopulars went down faster beyond the wall and with some eclat!
So say the party leader and his deputy or one other senior grandee may remain holding the banner for a while, but without their party gaining sufficient representation, they'd be about as effective as a chocolate teapot.
PR also shifts the focus from personalities to policies and the substance behind them.
Perhaps the strongest aspect of the system is, however, its wider representative reach, which both brings the extreme, or fringe, views into the mix and allows for them to be debated and challenged in the sphere of public politics. This is both more democratic, and is much better than letting some of these views to be left simmering under the surface and internet forums, as is the case with the Westminster model.

They have the power to both modify and reject legislation. Further, national parliaments need to ratify and write anything coming from the EUP in compatibility with the relevant national legislation already in place. From major treaties to unfair trade deals, both the EUP and the national parliaments can send the bills back to the drawing board or stop them completely. We are also quite capable of using our veto powers, when we totally disagree.
The Commission, one member per member state, I might add, has the legislative initiative, sure, but it is balanced by the strategic oversight body of the European Council -- a body for the freely elected leaders of all the member states and its own president, who propose the EC president, and take into account recent parliamentary elections.
The European Parliament can dissolve the Commission; the national parliaments can vote out unpopular national leaders, hence removing them from the Council.
